For information on connecting the power, also refer to the diagrams relating to "System
integration". The direction of motion of the primary or secondary section is positive if the
primary section is connected to phase sequence U, V, W. See "Direction of motion of the
motor (Page 35)".
Number of conductors and cable cross-sections
Cables that are connected to the motor must have four conductors for the power cable / four
conductors for the signal cable. The cross-section for each of the signal cable conductors is
0.5 mm
the motor. The rated current of the motor must be less than the current carrying capacity of
the cable according to DIN EN 60204-1 (laying system C). The table below specifies the
maximum permissible rated current of the motor for different cross-sections of the power
cable conductors.
