Tab. 4.28 Permissible cable lengths on the CMMP-AS-...-M0
1. To keep leaked current and losses in the motor cable as low as possible, the motor controller
CMMP-AS-...-M0 should be placed as close to the motor as possible (è Chapter 4.13.5 è Page 55).
2. Motor and encoder cable must be screened.
3. The screening of the motor cable is attached to the housing of the motor controller CMMP-AS-...-M0
(screened connection terminals, spring clips). The cable screening is also always attached to the
corresponding motor controller to prevent leaked current flowing back to the controller which
caused it.
4. The mains-side PE connection is connected to the PE connection point of the power supply [X9] and
to the PE connection of the housing.
5. The PE internal conductor of the motor cable is connected to the PE connection point of the motor
connection [X6].
6. Signal lines must be separated as far as possible from the power cables. They should not be routed
parallel to one another. If crossovers are unavoidable, they should be made as close to vertical (i.e.
at a 90° angle) as possible.
7. For unscreened signal and control lines, safe/reliable operation cannot be guaranteed. If they must
be used, they should at least be twisted.
8. Even screened cables always have short unscreened parts at both ends (unless a screened plug
housing is used).
In general:
– Connect the inner screenings to the pins of the plug connectors provided for the purpose; length
maximum 40 mm.
– Length of the unscreened wires with self-made cables, maximum 35 mm.
– Connect entire screening on the controller side flush to the PE terminal; maximum length 40 mm.
