The motoring current limit applies in either direction of rotation when the machine is producing motoring torque. Similarly the regen current limit
applies in either direction when the machine is producing regenerating torque. The symmetrical current limit can override either motoring or
regenerating current limit if it is set at a lower value than either limit.
