Thorlabs' PIA13 Piezoelectric Inertia Actuator provides high-resolution linear motion control with a long piezo-controlled translation range in a compact package. It can support loads up to 2.5 kg (5.51 lbs) and preloads up to 30 N with typical movements of 20 nm and no backlash. The step size can be adjusted up to 30% to a maximum of approximately 30 nm using the KIM101 Controller and Kinesis® software. However, due to the open-loop design, hysteresis, and application conditions, the achieved step size of the system can vary over 20%. An external feedback system will need to be used to overcome this variance.

This actuator has a Ø3/8" (Ø9.5 mm) mounting barrel with a 3/8"-40 thread on the front of the barrel for compatibility with our wide range of translation and rotation stages. For compatibility with 1/4"-80 threaded mirror mounts see our 10 mm travel piezo inertia actuator. The actuator is self-locking when at rest and when there is no power supplied to the piezo, making the actuator ideal for set-and-hold applications that require nanometer resolution and long-term alignment stability. Manual adjustments can be made at any time, as long as the piezo is not actively translating the screw, by using the rear-located thumbscrew or with a 5/64" (2 mm) hex key.

  • This value can vary over 20% due to component variance, change of direction, and application condition.
  • This can be adjusted up to 30% in both directions using the KIM101 Controller and Kinesis Software.
  • This can be Adjusted using the KIM101 Controller and Kinesis Software.
  • Using the KIM101 Inertia Piezo Controller
  • The axial force applied to the drive tip to achieve the specified step size. A minimum of 5 N is recommended to enhance stepping behavior.
  • A higher maximum load is possible but it may adversely affect the typical step size.

Powered by a 10 mm (0.39") long discrete piezo stack, the actuator can operate at speeds of up to 3.5 mm/min. The design of the piezo motor will rotate the tip of the lead screw during translation. As shown in the image to the right, the control cable for each actuator can be rotated up to 110° for space-constrained applications.

For information on the design of our piezo inertia "slip-stick" motor actuators, please see the complete presentation here.

Required Controller
The KIM101 Controller is required to operate our PIA13 Piezo Inertia Actuator; the actuator cannot be operated using a standard piezo controller. The KIM101 has an internal sawtooth voltage signal generator capable of sending sub-millisecond pulses (steps) with controllable amplitudes from 85 V to 125 V. The driver features four channels and is capable of single- or dual-channel operation, making the controller ideal for applications involving multiple motorized actuators, such as beam steering.

  • Two Mounting Options: Ø3/8" Smooth Barrel or 1/4"-80 Threaded Barrel
  • Compatible with Mirror Mounts and Translation Stages using 1/4"-80 Thread or 3/8" Mounting Block
  • Also Available in 6 mm and 25 mm Travel Versions

Our ZST Actuators provide smooth, precise linear motion control in a package measuring 123.0 mm (4.84") in length. Powered by a small-diameter, two-phase, bi-polar stepper motor, these actuators operate at speeds of up to 2.0 mm/s. The non-rotating drive tip reduces wear and friction and improves smoothness of motion by removing rotational contact at the tip.

These actuators incorporate a stepper motor that provides sufficient torque for loads up to 40 N (8.99 lb). They allow very small step sizes over the entire travel range, delivering greater flexibility with low (<15 µm) backlash and fine resolution. The design incorporates a 41:1 gear reduction head which, when combined with the 3072 microsteps per revolution offered by the KST101 stepper motor driver, gives a theoretical travel per microstep of 0.5 nm (see the Caluclations tab for details).

The ZST213 actuator has a 1/4"-80 threaded barrel that can be mounted to any manual mirror mount for stage with 1/4"-80 threads, while the ZT213B actuator has a Ø3/8" barrel for compatibility with a wide range of translation and rotation stages, including our popular MT1 Translation Stages. Simply remove the existing manual adjuster from the mount, and screw in our ZST Actuator.

How to calculate the linear displacement per microstep

Each member of the ZST200 series of motors has 24 full steps per revolution, and when driven by the KST101 drivers, there are 2048 microsteps per full step. Hence, there are 49,152 microsteps per revolution of the motor. The output shaft of the motor goes into a 40.866:1 gear head. This requires the motor to rotate 40.866 times to rotate the 1.0 mm pitch lead screw one revolution. The end result is the lead screw advances by 1.0 mm. To calculate the linear displacement of the actuator per microstep, use the following:


Linear displacement of the lead screw per microstep:

Number of Microsteps x Gearbox Ratio = 49,152 x 40.866 = 2,008,645.63

The linear displacement of the lead screw per microstep is

1.0 mm / 2,008,645.63 = 0.49 x 10-6 mm = 0.5 nm

One last thing: I am running 32-bit APT User for use in a 64-bit environment. It's possible that Thorlabs has not updated this version of APT User to include the firmware updates for KST101's. All I can say is that my version (v3.21.1) only includes firmware v1.0.2 for the KST101. At any rate, there is nothing more I can do here to alleviate the problem. As it is, the hardware fails to perform according to its own published specifications and is therefore unusable by me, at least in its current state.
fwilliams  (posted 2017-09-28 08:02:29.833)
Sorry, I should've included the fact that I am already using the most-recent version of APT User (v3.21.1). Nonetheless, when I flash the firmware to the KST101, the firmware utility reports that the firmware revision level is v1.0.2, NOT v1.0.6.
tfrisch  (posted 2017-10-02 07:19:46.0)
Hello, we will reach out to you through your open ticket to discuss this.
fwilliams  (posted 2017-09-26 15:30:53.1)
FOLLOWUP: Using the firmware-update utility found in the APT User program folder, I determined that my KST101's are running firmware v1.0.2. However, in the APT User change log, the latest firmware for the KST101 is listed as v1.06, which includes the description: "Fixed bug to respond correctly when MoveStop commands are completed." It seems that I need this firmware update - how can I obtain it?
bwood  (posted 2017-09-28 08:10:31.0)
Response from Ben at Thorlabs: Thank you for your feedback. You can update the firmware of your KST101 with the Firmware Update Utility which is installed with APT. It should be found next to APT on your computer. I would recommend making sure you are using the newest version of APT, when you update the firmware.
fwilliams  (posted 2017-09-26 14:32:19.267)
Now that I am using the ZST213 in my new system, I find that it drifts much more than the old ZST13 did. The ZST213 is less precise, and struggles at making small jogs (unlike the older actuator, which delivers repeatable and deterministic jogs of 75 nm all day). I am able to make a direct comparison between the two actuators, because I have an older system on the same bench that is identical except for the fact that it uses ZST13's instead of the newer ZST213. If I try to make a jog of 75 nm (say) with the ZST213, I often see no movement (other than an uncorrelated random drift). If I keep sending Jog commands, all of a sudden the system will move a significant distance, slowly coming to a stop. I have tried playing with the Jog settings (velocity, accn, immediate vs. profiles stopping, etc.), but nothing seems to improve the situation. I am using KST101 cubes to control the ZST213's. Is there a firmware fix for this problem?
bwood  (posted 2017-09-28 08:20:26.0)
Please find my response above.
fwilliams  (posted 2017-06-28 11:08:39.82)
Never mind - I figured out my problem. I had the wrong setting for the lead-screw pitch. I was using 0.5 mm (the pitch of the now-obsolete ZST13B) instead of the correct value of 1.0 mm for the ZST213B. When I said in my earlier post that I use APT User, I actually run it from within a Matlab program that calls APT User. I developed this program with the old ZST13B. I'm now setting up a new system using this Matlab program, and had neglected to update the settings for the newer actuator. Sorry about the confusion.
tfrisch  (posted 2017-07-01 11:40:20.0)
Hello, thank you for this followup. I'm glad you were able to find a solution, please let us know if you need anything further.
fwilliams  (posted 2017-06-27 14:48:18.903)
I am running a ZST213B with a KST101 controller, using the APT User interface. I am finding that the motion is completely uncalibrated. For example, after homing to zero, entering a command to move to 6 mm (say) will cause the actuator to move the full length of travel (i.e., ~ 13 mm). The only way I can get the actuator to move an approximately correct distance is to adjust down the Gearbox Ratio to something like 19 (it should be 41). Just so there's no question, I ran APT Config before running the actuator with APT User, making sure to choose the proper stage designation ["ZST213(B)"] when I associated the stage with the controller's serial number. Is there a way to get the actuator/controller to behave correctly?
tfrisch  (posted 2017-07-01 11:40:26.0)

Is there an adapter fitting to convert the 1/4"-80 Threaded Barrel to a 3/8" Smooth Barrel? I'd really like to use one of these with either a mirror mount (needs 1/4"-80 threaded) or a translation stage (needs 3/8" smooth), rather than having to buy two.

  • Compact, Bi-Polar Stepper Motor Actuator:
    • ZFS13: 89.5 mm (3.52") Long when Retracted
    • ZFS13B: 85.5 mm (3.36") Long when Retracted
  • Manual Adjustment via Rear-Located Thumbscrew
  • Non-Rotating Drive Tip
  • Compatible with Mirror Mounts and Translation Stages using 1/4"-80 Thread (ZFS13) or 3/8" Mounting Block (ZFS13B)
  • Also Available in 6 mm and 25 mm Travel Versions

Our ZFS13 and ZFS13B Actuators provide smooth, precise linear motion control in a sleek, compact package measuring just 89.5 mm (3.52") or 85.5 mm (3.36"), respectively, in length when fully retracted. This compact profile reduces the distance between the end of the actuator and optomechanical components, keeping the center of mass closer to the contact point than the ZST actuators featured above.

Powered by a small-diameter, two-phase, bi-polar stepper motor, these actuators operate at speeds of up to 2.0 mm/s. The non-rotating drive tip reduces wear and friction and improves smoothness of motion by removing rotational contact at the tip. If power is not supplied to the actuator, manual adjustment is achievable using the rear-located thumbscrew. The actuator motor can be damaged if this thumbscrew is rotated while power is being supplied.

The ZFS13 actuator has a 1/4"-80 threaded barrel that can be mounted to any manual mirror mount for stage with 1/4"-80 threads, while the ZFS13B actuator has a Ø3/8" barrel for compatibility with a wide range of translation and rotation stages. Simply remove the existing manual adjuster from the mount, and screw in our ZFS Actuator.

These actuators incorporate stepper motors that provides sufficient torque for loads up to 40 N (8.99 lb). The actuators allow very small step sizes over the entire travel range, delivering greater flexibility with low (<15 µm) backlash and fine resolution. The design incorporates a 400:9 gear reduction head which, when combined with the 49,152 microsteps per revolution offered by the KST101 stepper motor driver, gives a theoretical travel per microstep of 0.46 nm (see the Caluclations tab for details).

How to calculate the linear displacement per microstep

The ZFS series of motors has 24 full steps per revolution, and when driven by the KST101 drivers, there are 2048 microsteps per full step, giving 49,152 microsteps per revolution of the motor. The output shaft of the motor goes into a 400:9 gear head. This requires the motor to rotate 44.445 times to rotate the 1.0 mm pitch lead screw one revolution. The end result is the lead screw advances by 1.0 mm.


Linear displacement of the lead screw per microstep:

Number of Microsteps x Gearbox Ratio = 49,152 x 44.445 = 2184560.64

The linear displacement of the lead screw per microstep is

1.0 mm / 2184560.64 = 0.46 x 10-6 mm = 0.46 nm

These Motorized Actuators are engineered for use with optical positioning devices. They offer high resolution in a lightweight package, which makes them ideally suited for demanding optical laboratory automation applications. The Z812 delivers 12 mm of travel and has been designed as a replacement for the former-generation Z712 motor.

Commercial limit switches have been added to provide overdrive protection and accurate home positioning. The motor in the Z8 provides a motion velocity of 2.3 mm/s. The precision of the encoder (512 counts/rev) results in a minimum resolution of about 29 nm.

The Z812 has been designed specifically to replace the manual adjusters in stages and mirror mounts that have 1/4"-80 screw-in fittings, while the Z812B is for use with 3/8" barrel clamps (e.g., the 1/2" manual micrometer in the MT Series Translation Stages). Simply remove the existing manual adjuster from the mount, and screw in our Z8 actuator. The photo below shows a KS2 mirror mount with one of the thumbscrew actuators replaced by a Z812 motor actuator.

  • Recommended
  • At 2.6 mm/s, velocity ripple and distortion of the acceleration/deceleration profile may occur. For improved control, the maximum velocity should be limited to 2.3 mm/s.
  • The nominal motor drive voltage is 6 V. Voltages up to 12 V can be used with pulse width modulation (PWM) controlled outputs.

In addition to the Z812 and Z812B motorized acutators, we also offer the Z812V and Z812BV vacuum-compatible versions (sold below), which are rated for use down to 10-6 torr and are shipped with a 1.6' flat ribbon cable, IDC connector, and converter cable for use with our KDC101 controller. For applications with different travel requirements, please see our 6 mm Z806 and 25 mm Z825 actuators. 

The KDC101 DC Servo Controller is the required driver for the Z8 series actuators. Please note that older TDC001 units will require a firmware upgrade to V1.0.10 or later, before they can be used with the Z8 series motors. An upgrade is included with the latest APT server software, which can be downloaded here.

Z812_KS2
The units are shipped with a non-detachable 1.6' (0.5 m) cable. A 2.5 m (8 ft) extension cable (PAA632) is available separately.

How to Calculate the Linear Displacement per Encoder Count

For the Z812 and Z812B, there are 512 encoder counts per revolution of the motor. The output shaft of the motor goes into a 67:1 planetary gear head. This requires the motor to rotate 67 times to rotate the 1.0 mm pitch lead screw one revolution. The end result is the lead screw advances by 1.0 mm.

The linear displacement of the actuator per encoder count is given by

512 x 67 = 34,304 encoder counts per revolution of the lead screw,

whereas the linear displacement of the lead screw per encoder count is given by

1.0 mm / 34,304 counts = 2.9 x 10-5 mm (29 nm).

We decided to include the connector even though customers using the product in a vacuum chamber will usually need to cut the connector of in order to connect to the feedthrough. Reason for shipping the item with the connector is that it will allow the end user to easily test the device before implementing it into the setup. The cable itself is a PTFE coated ribbon cable. In order to achieve the best possible performance in a vaccuum chamber I would suggest that we offer a custom actuator with a longer ribbon cable. With this you wont need to use any cable connectors inside the chamber.

Does the Z612BV come with the same ribbon connector as the original Z612? Do you provide extension ribbon cables? Thank you.

  • Recommended
  • At 2.6 mm/s velocity ripple and distortion of the acceleration/deceleration profile may occur. For improved control, the max velocity should be limited to 2.3 mm/s.
  • The nominal motor drive voltage is 6 V. Voltages up to 12 V can be used with pulse width modulation (PWM) controlled outputs.

Features

  • 6 VDC Servo Actuator
  • Submicron Resolution
  • Maximum Velocity: 2.3 mm/s
  • Drop In Replacement for Most 12 mm Manual Actuators
  • Compatible with 1/4"-80 Thread (Z812V) and 3/8" Barrel-Fitted (Z812BV) Stages and Mounts
  • Limit Switches for Zero Datum and Actuator Protection
  • Rated Down To 10-6 Torr.
  • Also Available in 6 mm and 25 mm Travel Versions

The Z812V and Z812BV offer all the features and specifications of the standard Z812 actuators described above with the added benefit of being vacuum compatible down to 10-6 Torr. These motors feature vacuum rated servo motors, phosphorus bronze internal coupling mechanism and mounting bush, and high vacuum grease.

These actuators are shipped with a 1.6' (0.5 m) vacuum-compatible flat ribbon cable with IDC connector. The cable has a 0.05" (1.27 mm) pitch, 28 AWG stranded conductors, and Fluorinated Ethylene Propylene (FEP) insulation. A converter cable for use with the KDC101 controller is also supplied, but it is not vacuum compatible and should only be used outside the chamber.

For applications with different travel requirements, please see our 6 mm and 25 mm actuators. For vacuum-compatible versions of our stages and mirror mounts, please contact Tech Support.

The KDC101 DC Servo Controller is the required driver for the Z8 series actuators. Please note that previous generation TDC001 units will require a firmware upgrade to V1.0.10 or later before they can be used with the Z8 series motors. An upgrade is included with the latest APT Server software, which can be downloaded here.

How to Calculate the Linear Displacement per Encoder Count

For the Z812V and Z812BV, there are 512 encoder counts per revolution of the motor. The output shaft of the motor goes into a 67:1 planetary gear head. This requires the motor to rotate 67 times to rotate the 1.0 mm pitch lead screw one revolution. The end result is the lead screw advances by 1.0 mm.

The linear displacement of the actuator per encoder count is given by

512 x 67 = 34,304 encoder counts per revolution of the lead screw,

whereas the linear displacement of the lead screw per encoder count is given by

1.0 mm / 34,304 counts = 2.9 x 10-5 mm (29 nm).

The vacuum-compatible cable integrated with the Z812V and Z812BV is terminated in a Female IDC 10-Pin socket connector. A short converter cable, which adapts this female IDC socket connector to a D-Type male HD15 pin connector, is included with the Z812V and Z812BV to facilitate connecting the actuator to the recommended KDC101 controller. This converter cable, whose terminating connectors are shown at right, is not vacuum compatible.  Information describing the pin assignments for both the female IDC socket and Male D-Type HD connector (when it is connected to the female IDC socket connector) follows.
