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 autodetect peripheral axes are designed to be used effortlessly with Zaber's line of autodetect controllers.
The LRT-EC includes onboard memory that allows Zaber's controllers to autodetect the model and set
reasonable parameters. See the Protocol Manual for more information on how to modify the settings. Damage to
the axis may result if the settings are not correct. To use your Zaber peripheral with a third-party controller, review
the motor, sensor, and encoder specifications and pin-outs carefully.
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 lead screw thread. These will reduce the performance of the device
below stated specifications.
Conventions used throughout this document
Fixed width type indicates communication to and from a device. The symbol indicates a carriage
return, which can be achieved by pressing enter when using a terminal program.
An ASCII command followed by (T:xx) indicates a legacy T-Series Binary Protocol command that
achieves the same result. For example,
move abs 10000 (T:20:10000) shows that a move abs ASCII command can also be achieved with
Binary command number 20.
Not all ASCII commands have an equivalent Binary counterpart.
Device Overview
AutoDetect
Your LRT-EC peripheral is equipped with AutoDetect, a feature that allows a Zaber controller to automatically
configure its settings for the peripheral when it is connected.

Important: The controller should always be powered down before disconnecting or connecting your LRT-
EC peripheral.
To connect the peripheral to a controller:
1. Power off the controller.
2. Connect the LRT-EC peripheral.
3. Power on the controller.
4. The controller will activate the peripheral shortly after it is powered on.
Connectors
Recommended controller(s) for your LRT-EC peripheral are provided in the product specifications. Zaber's
controllers and peripherals are designed for ease of use when used together. Optimal settings for each peripheral
are automatically detected by Zaber's controllers when the device is connected.
For reference, the pinout for the peripheral cable connectors is shown below:

Alternate Controllers
The LRT-EC can be controlled by any 2-phase stepper motor controller with limit sensor and appropriate encoder
input. We do not recommend using your own controller unless you are familiar with how to control a
stepper motor with hall sensor limit switches. Damage to the stage due to incorrect wiring is not covered by
warranty.
Motors & Encoders
For motor and encoder information see the LRT-EC product page
Limit Sensors
Hall effect sensors are used in the LRT-EC as home sensors. The Hall sensors used are part number
A1120LLHLT-T made by Allegro. Click here for data sheet. Your controller should be configured so the stage
stops immediately (quick deceleration) when the sensors are triggered.
PCB wire colour code:
o3.6-24 Vdc input - red
oHome signal - yellow
oAway signal - white
oGround - 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 each
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 10 kΩ and for the bypass capacitor is 0.1
uF to 1 uF. The larger the capacitance, the better the noise filtering but the slower the response time.

Installation
Physical Installation
Secure stages with M6 (or 1/4"-20) socket cap screws, 35 mm or longer.
Two stages can be mounted directly in XY configuration.
Tip: To obtain the best pitch, roll, yaw and runout accuracy, mount the stage to a known flat, stiff surface.
Our tests were performed on a granite table, grade A flatness.
Tipping Hazard! Ensure stage is fastened to a secure surface before mounting load on carriage. An
unmounted stage with a load presents a tipping hazard. Ensure loads are mounted securely to the carriage of the
stage.
Back-driving Hazard! When mounting stages vertically where they will lift a load, do not exceed the values
in the following table. Exceeding this load could backdrive the device, especially during loss of power, and could
damage its controller and cause injury.

Maintenance
We recommend greasing the linear bearings to prolong service life. Many factors affect the lifetime of the grease
and bearings including temperature, contamination, and loading configurations but the following chart provides a
guideline. Grease with Shell Gadus S2 V220 2 or similar lithium thickened petroleum grease.
Remove dust cover
Careful, dust cover edges are sharp!
Pinch Hazard! You will need to move the stage with the power on while greasing. Be careful not to squish
anything, especially fingers or hands, between the carriage and the end plates.
Remove the dust cover clamps at each end of the stage by removing their M3 screws.

Remove the carriage ramps by removing their screws.
Slide out the carriage cover.
Slide out the dust cover. CAUTION! DUST COVER EDGES ARE SHARP!
Insert angled syringe tip into grease hole in bearing end cap. With the power on and using the manual
control knob (if equipped), move the stage about 100 mm (4") while squeezing grease in from the syringe.

Don't drive the carriage close to the ends of the stage where the risk is greater of squishing the syringe or
your fingers. Repeat with the other three end caps.
Reinstall dust cover
Slide dust cover into carriage, above angled sliding pads but below thin channel near the top. Position the
dust cover so it's about even at both ends
Install one carriage end ramp and slide the top sheet in the thin channel near the top.
Attach the other carriage end ramp.

Position the dust cover so it comes close to the clamp holes at each end.
Loosely attach the clamps at each end. Run the stage back and forth once to position the dust cover.
Gradually tighten the clamp screws, alternating between the two at each clamp. If part of the dust cover
isn't seated properly, loosen the nearest clamp and re-tighten.
