Disclaimer
Zaber’s devices are not intended for use in any critical medical, aviation, or military applications or situations where a product's use or failure could cause personal injury, death, or damage to property. Zaber disclaims any and all liability for injury or other damages resulting from the use of our products.
Precautions
Zaber’s motion control devices are precision instruments and must be handled with care. In particular, moving parts must be treated with care. Avoid axial loads in excess of the rated thrust load, axial and radial impact, dust and other contaminants and damage to the leadscrew thread. These will reduce the performance of the device below stated specifications.
Installation
Physical Installation
Mounting
There are several options available for mounting Zaber stages. Use the mounting holes in the bottom to mount to a surface or to another stage. You might have to move the carriage to access the bottom mounting holes. Some stages have mounting holes in the end plates for mounting vertically. Mounting screws are included with most stages.
Caution: Some stages have threaded through-holes in the top mounting plate of the carriage. Be sure not to install mounting screws too deep, causing them to interfere with inside parts of the stage.
Grounding
To prevent damage to the device due to static buildup, the device should be properly grounded.
Failure to ground the unit may result in the unit shutting down unexpectedly or ceasing to communicate with the computer. This problem can be minimized by not touching the unit during operation. If the unit fails due to static discharge, unplugging it and plugging it back in or sending a Restore Settings command will usually fix the problem.
Most Zaber devices are grounded via the shield wire of the data cables. This should normally provide a path to ground via the computer. For units which are being used without a computer, a ground lead should be connected to the shield of one of the data cables.
Operation
The LSQ-T3 stages are designed to be controlled with the A-MCA series chopper drive controllers. It is important to know the peripheral id of your motor. If you ever need to restore the correct settings for your LSQ-T3 stage, send restore settings (command 36) with the peripheral ID in the data field.

Alternate Controllers
The actuators may be controlled by any 2-phase stepper motor controller with home sensor input. Warning: Operating the stage without correctly wiring up the home sensor can cause permanent damage to the sensor. We do not recommend using your own controller unless you are familiar with how to control a stepper motor with a hall sensor limit switch. The following information is provided for reference only. Damage to the stage or hall sensor due to incorrect wiring is not covered by warranty.
Motor
The LSQ stage uses a size 17 stepper motor.
- 1.2 A / Phase
- 3.3 Ω / phase
- 2.8 mH / phase
Home Sensor Wiring
A Hall effect sensor is mounted in the device for use as a home sensor. It is part number A1122LUA-T made by Allegro. Click here for data sheet. Your controller should be configured so the stage stops immediately (little deceleration) when the home sensor is triggered.
- Wire colour code:
- 3.6-24 Vdc input - red
- Home signal - yellow
- Ground - black
The Hall sensor has an open-collector output. The default output is high impedance when the Hall sensor is not active. When the sensor detects a magnet, the Hall sensor pulls the output low to ground.
If you are not using a Zaber controller, ensure that your controller has a pull-up resistor on the output line of the Hall sensor as shown in the diagram. The bypass capacitor is optional, but may help to eliminate false triggering in noisy environments. The typical value for the pull-up resistor (RLOAD) is 10k and for the bypass capacitor is 0.1uF to 1uF. The larger the capacitance, the better the noise filtering but the slower the response time.
Warranty and Repair
For Zaber's policies on warranty and repair, please refer to the Ordering Polices

All standard Zaber products are backed by a one-month satisfaction guarantee. If you are not satisfied with your purchase, we will refund your payment minus any shipping charges. Goods must be in brand new saleable condition with no marks. Zaber products are guaranteed for one year. During this period Zaber will repair any products with faults due to manufacturing defects, free of charge.
Custom products
Custom products are any part numbers containing the suffix ENG followed by a 4 digit number. Each of these products has been designed for a custom application for a particular customer. Custom products are guaranteed for one year, unless explicitly stated otherwise. During this period Zaber will repair any products with faults due to manufacturing defects, free of charge.
How to return products
Customers with devices in need of return or repair should contact Zaber to obtain an RMA form which must be filled out and sent back to us to receive an RMA number. The RMA form contains instructions for packing and returning the device. The specified RMA number must be included on the shipment to ensure timely processing.
