3.2.2
Intermediate circuit coupling, DC power supply
Intermediate circuit
coupling:
It is possible to connect CMMP-AS series servo positioning control-
lers with each other at the same nominal intermediate circuit volt-
age. The PFC stage must be deactivated for this.
It is possible to couple the intermediate circuit voltage of the
CMMP-AS servo positioning controller to servo positioning
controllers from the CMMP family. The PFC stage must be
deactivated for this.
Intermediate circuit coupling of CMMP-AS series servo positioning
controllers with activated PFC is still under preparation.
DC power supply:
Direct DC power supply via the intermediate circuit terminals, with-
out a mains grid connection, is possible with voltages 60 VDC.
The digital motor temperature monitoring only begins functioning
at an intermediate circuit voltage of 120 VDC. Below this voltage,
the digital motor temperature sensor is always recognised as open.
3.2.3
Mains fuse
A single-phase 16 A slow-blow (B16) circuit breaker must be installed in the mains power
supply cable.
Note
If CE certification is required, the following specifications for mains
fusing must be observed:
Listed Circuit Breaker as per UL 489, rated 277 Vac, 16 A, SCR 10 kA.
3.3
Brake chopper
A brake chopper with a braking resistor is integrated in the power output stage. If the per-
mitted load capacity of the intermediate circuit is exceeded during the energy recovery, the
braking energy may be converted to heat by the internal braking resistor. The brake chop-
per is actuated with software control. The internal braking resistor is protected against
overloading via software and hardware.
If the rating of the internal braking resistor is inadequate for certain applications, then this
can be switched off by removing the jumpers between pins BR-CH and BR-INT of plug [X9].
An external braking resistor must then be connected between pins BR-CH and ZK+. This
braking resistor must not be rated lower than the specified minimum value (see Table A.10
page 103). The output is fused against a short-circuit in the braking resistor or the braking
resistor wiring.
