4.2.6.4 Motor cable length for parallel operation of motors

The resulting motor cable length for parallel operation of motors, or parallel installation
with multiple cables arises from the following formula:
resulting motor cable length = ∑single cable length x √Number of motor cables

on the ambient conditions such as bundling and temperature.
Protect motor against voltage peaks !
Drive controllers switch at the output with dV /dt ≤ 5kV/µs. Voltage peaks
that endanger the insulation system at the motor can occur especially in
case of long motor cables (> 15 m). A motor choke, a dv/dt-filter or sine-
wave filter can be used for protection of the motor.
faulty behaviour of the motor !
The connecting-up instructions of the motor manufacturer are always
generally valid !
