These cyclic values therefore limit the torque setpoint at the speed controller output / torque
input or indicate the instantaneous maximum possible torque. If the torque setpoint is limited
in the Motor Module, this is indicated via the following diagnostic parameters:
● r1407.8 CO:/BO: Status word speed controller: Upper torque limit active
● r1407.9 CO:/BO: Status word speed controller: Lower torque limit active
