Note
When the load voltage is switched on, ensure that the reference potential (N) is
switched before the phase (L1). This can be achieved through:
– unswitched reference potential (N)
– use of fuses with leading N when switching of the reference potential is specified.
DC supply - intermediate circuit coupling
A direct DC power supply can be used for the intermediate circuit as an alternative to AC power or for
achieving intermediate circuit coupling.
The intermediate circuits of several identically constructed motor controllers (CMMP-AS-...-3A-M0/-M3
or CMMP-AS-...-11A-P3-M0/-M3) can be connected via the terminals ZK+ and ZK- at plug connector
[X9]. Coupling of the intermediate circuits is useful in applications where high braking energies occur or
where motion must still be performed when the power supply fails.
Note
For 1-phase motor controllers (CMMP-AS-...-3A-M0), the PFC step must be deactivated
when the motor controller is coupled through the intermediate circuit.
Note
If the intermediate circuits are coupled, it is imperative that all of the motor controllers
are supplied via the same phase (e.g. L1) è Example Fig. 4.6.
Otherwise, the motor controllers will be damaged due to the resulting voltage at the
rectifiers.
The maximum number of coupled motor controllers is limited by the power of the sup
ply. Pay attention to a symmetrical load of the network here.
