50 +12V, 250mA (maximum)
+5V, 250 mA (maximum)
+5V supply available from the PC.
+12V, 250 mA (maximum)
+12V supply available from the PC.
–12V, 250 mA (maximum)
–12V supply available from PC.
Amplifier Enable Output
Open-drain output with 1KΩ pull-up resistor to +5 volts. This output is
asserted active True when the axis is in the motor ON state and False for
the motor OFF. The actual TTL level is user-configurable.
Amplifier Fault Input
The Amplifier Fault input is pulled-up to +5 volts with a 1KΩ resistor. The
active true state is user-configurable.
Analog Ground
Servo digital-to-analog (DAC) ground.
Cable Interlock Input
The Cable Interlock input is pulled-up to +5 volts with a 1KΩ resistor. If
this input is a logical HIGH then is assumed that the 100-pin cable is not
properly fastened and a Cable Interlock error will be generated.
