Motor-side power components

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 charge/discharge currents that also occur on the output of the

Motor Module when long motor cables are used are reduced.

Motor reactors can be operated in the VECTOR and SERVO control modes.

Prerequisites

● Ambient temperature 40 °C

● Pulse frequency f

● Output frequency f

● Supported in STARTER from Version 2.4 up to 1 motor reactor

● Supported in STARTER from Version 2.5 up to 3 motor reactors

In SERVO control mode, the maximum output frequency of the converter must not be higher

than the maximum motor reactor frequency.

Danger to life if the fundamental safety instructions and remaining risks are not carefully

If the fundamental safety instructions and remaining risks in Chapter 1 (Page 25) are not

observed, accidents involving severe injuries or death may occur.

• Adhere to the fundamental safety instructions.

• When assessing the risk, take into account residual risks.
