4-Wire Motor Wiring
Specifications
The following specifications apply only to the MID-7604/7602. To obtain a complete system
specification, you must account for your motion controller. Refer to your controller specifications to
determine overall system specifications.
Some signals have compatibility defined as signal pass-through, which means the MID-7604/7602 may
have passive filtering on these signals but will not affect the voltage range or current handling capability.
Consult your motion controller specifications to determine the allowable voltage range and logic level
compatibility of the signal.
