CHAPTER 1 OVERVIEW
This section contains diagrams of the jumpers and switches on the ACR2000 mother
board.
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 SIMM module outputs provide an analog control voltage
of
±
10 volts.
Stepper SIMM module outputs provide open-collector step and direction signals. There
are no pull-up resistors provided on the Stepper outputs.
Factory default jumper settings for the ACR2000 motherboard are highlighted within the
following jumper tables.
