If motor brakes are connected to the power modules or output stages, they must be swapped
as well (X344, X392, X393, X394, depending on the model. --> See Service Manual for Inverter
Systems and Motors)!
Background:
Motor brakes can be connected to current HEIDENHAIN power modules (inverter modules)
and compact inverters. The motor brake is also powered with 24 V via a connector on the inverter.
The trigger signals for the motor brakes are transmitted via the PWM bus.
