ABB ACS 600 - Power Factor Compensation Capacitors; Output Contactors

Chapter 2 – Installation and M/F Link Specification
2-2 ACS 600 Master/Follower Application Macro
External Control
Connections
The default parameter settings of the Master/Follower macro define the
control connections according to the circuit diagram below.
Figure 2-2 External control connections for the Master station. The markings of the NIOC board
terminals are given above. 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. See the ACS 604/607
Installation and Start-up Manual for the corresponding terminal markings.

No Fault
1)
Changes external speed reference source. In most
cases this is not required (can be left unconnected).
2)
Open switch = Constant speed is not activated.
Closed switch = Constant speed defined with Parameter
12.05 replaces the external speed reference.
3)
Changes the speed acceleration/deceleration ramp.
Note: Does not change the Follower ramp. In most
cases should be left unconnected.
4)
See 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
