Change of the direction of rotation in 2Q operation

In 2Q operation (controller 48XX or C180 = -1-), only one thyristor bridge of the
controller is active, i.e. the output terminal A can only carry positive voltage referred
to terminal B, on the condition that no active loads occur.

The direction of rotation of the motor is determined by the connection of the
armature cable to A and B and of the field cable to I and K. If the opposite direction
of rotation is required, take the following steps (depending on the actual value
feedback system):
