Figure 2-3 Follower fault information wiring. Note that the external input/output signals of ACS 601 and
ACS 604 units connect directly to the NIOC board I/O terminal blocks. On ACS 607, the I/O terminals
of the NIOC board are optionally wired to a separate terminal block (X2) at the factory.
ACS 600 Master/Follower Application Macro
The Follower does not send any feedback data via the serial Master/
Follower Link. Therefore it is highly recommended to separately wire
the Follower fault information back to the Master. The connection stops
both the Master drive and the Follower drives upon a Follower fault.
