Control Circuit Terminal Block Functions
Drive parameters determine which functions apply to the multi-function digital inputs (S1 to
S7), multi-function digital outputs (MA, MB), multi-function pulse inputs and outputs (RP,
MP) and multi-function photocoupler outputs (P1, P2). The default is called out next to each
terminal. Refer to
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. Setting parameter
A1-06 may change the I/O terminal function automatically from the factory setting.
. 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.
