Alternate Controllers
The VSR-E can be controlled by any 2-phase stepper motor controller with limit sensorand
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 VSR-E product page
Limit Sensors
Hall effect sensors are used in the VSR-E 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:
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 noisy environments. The typical value for the pull-up
