Supply system cables and motor cables
Project Planning
Permitted motor
cable lengths
The maximum motor cable length depends on:
•
Cable type
•
Voltage drop in the cable
•
Set PWM frequency P860/P861.
•
An HF... output filter can only be connected for VFC operating mode. If an HF... out-
put filter is connected, the cable length is not restricted by these limit values, but ex-
clusively by the voltage drop along the motor cable.
•
For encoder connection (VFC-n, CFC, SERVO): Maximum cable length for the en-
coder connection is 100 m at a capacitance per unit length
≤
120 nF/km.
The following data applies as an approximation:

the cable length is not restricted by these limiting values, but exclusively by the voltage drop along the motor cable.
