CHAPTER 1 OVERVIEW
This section contains diagrams of the jumpers and switches on the ACR1200
motherboard.
Encoder pull-up jumpers must be set correctly based on the types of encoders being used.
Failure to set these jumpers correctly may cause damage to the encoders or to the
receivers on the controller card.
There are no analog adjustment “pots” on the board. All analog gain and offset is under
software control. The analog outputs must be wired to differential control signal inputs
on a servo amplifier. The DAC outputs provide an analog control voltage of
±
10 volts.
Stepper outputs provide open-collector step and direction signals. There are no pull-up
resistors provided on the Stepper outputs.
DAC/Stepper Output configuration is set at the factory and is not field configurable.
Factory default jumper settings for the ACR1200 motherboard are highlighted within the
following jumper tables.
