4.2.5 Connection of the motor
4.2.5.1 Selection of the motor cable
The correct cabling as well as the motor cable play an important part in case of low pow-
er in connection with long motor line lengths. Ferrite cores and low-capacitance cable
(phase/phase < 65 pF/m, phase/screen < 120 pF/m) at the output have the following
e󰀨ects:
Longer motor cable lengths
Less abrasion of the motor gearbox by leakage currents
Better EMC properties
4.2.5.2 Cable-fed disturbances depending on the motor cable length at AC supply
The maximum motor cable length is depending on the capacity of the cable as well as
on the EMC emitted interference. The following data apply for operation under rated
conditions.
Size Voltage / V
Max. motor cable length shielded in accordance with EN 61800-3
