Alternate Controllers
The ASR-E 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
ASR-E product page
Limit Sensors
Hall effect sensors are used in the ASR-E as home and away sensors. The Hall sensors used are part number
A1120LLHLT-T made by Allegro.

. Your controller should be configured so the stage stops
immediately (quick deceleration) when the sensors are triggered.
PCB wire colour code:
o
3.6-24 Vdc input - red
o
Home signal - yellow
o
Away signal - white
o
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 each
Hall sensor as shown in the diagram. The bypass capacitor is optional, but may help to eliminate false triggering in
