Control Circuit Terminal Block Functions

Drive parameters determine which functions apply to the multi-function digital inputs (S1 to
S5), and multi-function digital outputs (MA, MB). The default is called out next to each
terminal in Figure 3.10.
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.
