Stepper and Servo Motor Drives
Motion
The specifications below apply to only the MID-76xx. Please refer to your controller specifications
to determine overall system specifications.
Some signals define compatibility as pass-through. This means the MID 76xx may have passive filtering
on these signals, but the signals do not affect the voltage range. Consult your motion controller
specifications to determine allowable voltage range and logic level compatibility of the signal.
