3.2.2 Connection of the motor
3.2.2.1 Selection of the motor cable
The correct cabling as well as the motor cable play an important part in case of low power
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 effects:
• longer motor line lengths
• lower abrasion of the motor bearings by leakage currents
• improved EMC characteristics
3.2.2.2 Motor line length at operation with DC voltage
The maximum motor line length at DC operation is basically dependent on the capacity of
the motor cable. The internal lter is not active at DC operation. External measures must be
taken here, if necessary. The following data apply for operation under nominal rating condi-
tions.
