Figure Notes:
Required to operate drive. STOP also used to clear a fault.
Use HIM Stop button to clear faults.
Contact Closure Input. Internal 5V supply. DO NOT apply external voltage.
When the ENABLE signal is lost, the drive output immediately shuts off and the
motor will coast to a stop.
A Start command will override any Jog command.
See Table 5.C on Page 5-31 for more information.
The recommended control signal wire is:
D Belden 8760 (or equiv.) - 18 AWG (0.750 mm
2
), twisted
pair, shielded.
D Belden 8770 (or equiv.) - 18 AWG (0.750 mm
2
), 3
conductor, shielded.
D Belden 9460 (or equiv.) - 18 AWG (0.750 mm
2
), twisted
pair, shielded.
Important: Control inputs to two or more drives must NOT
be connected in parallel.

Recommended practice is to run all signal wiring in a separate
steel conduit. The shield wire must only be connected at the
drive.
ATTENTION: Signal common is internally
connected to chassis ground. Do not use cable
shields as signal current paths.
