<P>PROBLEM TO BE SOLVED: To provide a load drive control circuit which can retard unintended operation of a load. <P>SOLUTION: When a motor is stopped, rotated forward or rotated reversely, a system control circuit drives a drive control circuit by delivering a motor control command combining the signals for notifying these operation requests to the drive control circuit, thus controlling rotation of the motor. In a combination of motor control command signals delivered from the system control circuit, (H, L, L) obtained from (L, L, L) by switching one of signal values (L, L, L) is set as a motor control command for reverse rotation preparation when motors M1 and M2 are reversed with reference to a motor stop request (L, L, L) as shown in an operation table 25. <P>COPYRIGHT: (C)2009,JPO&INPIT |
