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 in
Figure 3.
.
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.
Refer to Application Selection on page 96
. Failure to comply may result in death
or serious injury.
