Motor cable
You can calculate the permitted total length
of all motor leads connected in parallel as follows:
ltotal = Total length of the motor cables connected in parallel
lmax = Recommended maximum motor cable length for individual drives
n = Number of motors connected in parallel
No additional fusing is required if the cross section of the motor cable corresponds to that of the supply system lead. If the cross section of the motor cable is smaller than the cross section of the power supply cable, you must secure the motor cable against short circuit for the corresponding cross section. Motor protection switches are suitable for this purpose.
