Control Circuit Terminal Block Functions
Drive parameters determine which functions apply to the multi-function digital inputs (S1 to
S5), multi-function digital outputs (MA, MB, MC), and multi-function analog output (AM).
The default is called out next to each terminal in
.
WARNING! Sudden Movement Hazard. Always check the operation and wiring of control circuits after being
wired. Operating a drive with untested control circuits could result in death or serious injury.
WARNING! Confirm the drive I/O signals and external sequence before starting test run. Failure to comply
may result in death or serious injury.
NOTICE: Do not switch an input contactor more often than once every 30 minutes. Improper equipment
sequencing could shorten useful life of the drive electrolytic capacitors and circuit relays. Normally the drive
I/O should be used to stop and start the motor.
