Standstill Current Setting

If the host controller does not send the signal in half a second step, the drive will automatically enter power-saving semi-liquid state, phase current of motor winding will be reduced to half of the set, in this state, motor and drive power can be reduced, but the motor output torque is also reduced accordingly. Recovery automatically the output current rating when next pulse arrives.
