PURPOSE: To prevent malfunction of a drive system due to a transient hunting of a drive system power supply, which occurs when a main power supply is cut off by dropping the drive system power supply before a control system power supply.
CONSTITUTION: When a main switch is turned off. a PGS is switched and a relay is disconnected. Thus allowing a power supply (DC 24V) of a drive system to be dropped immediately. A power (DC5V) of a control system is reduced gradually. The power supply of the control system retains a voltage exceeding 90% for 20ms or longer for storing data after the main switch is tuned off. Thus, by dropping the power supply of the drive system to 0V, the drive system stops while the power supply of the control system retains a working voltage and the control system is functioning and no fluctuation during voltage drop occurs, thus preventing malfunction of a motor such as vibration from occurring.
