X9:
For operation of the motor controller CMMS-AS, the input voltage supply is connected to
the plug X9 at L1 (pin 1) and N (pin 2). The PE is connected to Pin 5. In the CMMS-AS plug-
in, the low-voltage monitoring must be adapted to the input voltage supply.
For the control section, a 24 V- voltage source is needed, which is attached to the +24 V
and 0 V terminals of the X9 plug.
An external brake resistance is connected to the contacts ZK+ and BR-CH.
X6:
The motor is connected to terminals U, V and W.
The motor temperature sensor (PTC, SI sensor or N/C contact) is connected to the +MTdig
and -MTdig terminals. (KTY81 ... KTY84 can be used as analogue temperature sensors. Not
in the FCT and not with EMMS-AS motors).
The motor brake is connected to the terminals Br+ and Br-.
The motors' protective conductor is connected to PE of the X6 plug.
The motor shield is conncected to the housing of the CMMS-AS using the shield connector.
X2:
The connection of the shaft encoder via the 15-pin D-sub plug to [X2] is roughly shown
schematically in the illustration Fig. 6.4.219H
The motor controller must first be wired completely. Only then can the operating voltages
be activated for the input voltage supply and the control section. If the polarity of the op-
erating voltage connections is reversed, or if the operating voltage is too high or the oper-
ating voltage and motor connections are reversed, the CMMP-AS servo positioning control-
ler will be damaged.
