ABB ACS355 series User Manual

294 Actual signals and parameters
8402 SEQ PROG
START
Selects the source for the Sequence programming
activation signal.
When Sequence programming is activated, the
programming starts from the previously used state.
If Sequence programming activation signal is lost, the
Sequence programming is stopped and all timers and
outputs (RO/TO/AO) are set to zero. Sequence
programming state (0168 SEQ PROG STATE) remains
unchanged.
If start from the first Sequence programming state is
required, the Sequence programming must be reset by
parameter 8404 SEQ PROG RESET. If start from the first
Sequence programming state is always required, reset and
start signal sources (8404 and 8402 SEQ PROG START)
must be through the same digital input.
Note: The drive will not start if no Run enable signal is
received (1601 RUN ENABLE).
