AC890PX AC Drive
Two Wire Logic Starting
Re-configure the DSE 890 default configuration(s) by connecting SETUP::SEQ & REF::SEQUENCING LOGIC :: REMOTE
REV OUT to SETUP::SEQ & REF::REFERENCE::REMOTE REVERSE.
This uses two inputs; RUN and REVERSE. The drive can operate in forward and reverse depending upon which switch is
closed. If both RUN and REVERSE are TRUE (24V) at the same time, both are ignored and the drive will stop.
Note that the SETUP::SEQ & REF::SEQUENCING LOGIC :: NOT STOP parameter is active (FALSE - not wired to),
meaning that the drive will only run while the RUN parameter is held TRUE.
