Motor reactors

6.1.1

Description

Motor reactors reduce the voltage stress on the motor windings by reducing the voltage
gradients at the motor terminals that occur when motors are fed from drive converters. At the
same time, the capacitive re-charging currents that additionally load the output of the Power
Module when longer motor cables are used are simultaneously reduced.
Prerequisites
● Ambient temperature 40 °C.
● Pulse frequency f
● Output frequency f
● If the total shielded cable length in the drive line-up is more than 350 m, a Voltage
● If the total unshielded cable length in the drive line-up is more than 560 m, a Voltage
● Only valid for vector operating mode.
● Supported in Starter from Version 2.4 up to 1 motor reactor.
● Supported in Starter from Version 2.5 up to 3 motor reactors.
