Chapter Overview
Description:
This chapter contains diagrams of the jumpers and connectors on the ACR8000 mother
and daughter boards.
Before optically isolated digital inputs and outputs can be used, the card must be
connected to an external 24 volt DC power supply. This connection is made at the PWR1
connector and is fused onboard at 3 amps to protect the controller card.
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 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 Acr8000 mother and daughter boards are
highlighted within the following jumper tables.
