Protect motor against voltage peaks !
Drive converters 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 protec
-
tion of the motor.
