This operation is shown in Fig.2.
The capacitor CSC connected to the CSC terminal is charged by the charging current ISL and its potential rises
as shown below :

When the motor is rotating, it is charged and discharged repeatedly by trigger pulse but if the motor rotation is
physically restrained, CSC discharge by trigger pulse is stopped and the potential further increases. During
this period, current flows continuously to the motor. If VSC (OSC potential) reaches VSCU, discharge starts
slowly and at the same time, the output is turned OFF to cur off current flowing to the motor. When the VSC
potential reaches VSCL, the output is turned ON to allow current flow to the motor and torque is generated.
As long as the motor rotation is kept restrained, this operation is repeated and the output is turned ON / OFF
at a ratio of nearly 1 : 5.
By this operation, the motor is heated and cooled and its temperature rise can be suppressed to a certain level.
If the motor is released from the above restraint, the motor is started to run again by the generated torque and
is continuously rotated by the generated trigger pulse.
