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.
