Control Circuit Terminal Block Functions
Drive parameters determine which functions apply to the multi-function digital inputs (S1 to S7), multi-function digital outputs
(M1 to M6), multi-function analog inputs (A1 and A2), and multi-function analog monitor output (FM, AM). The default
setting is listed next to each terminal in Figure i.10 on page 17.
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! Sudden Movement Hazard. 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 default setting. Failure to comply may result in death or serious injury.
