3.7 Control Circuit Wiring
NOTICE: Do not solder the ends of wire connections to the drive. Soldered wire connections can loosen over time. Improper wiring
practices could result in drive malfunction due to loose terminal connections.

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
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.
