<P>PROBLEM TO BE SOLVED: To forcibly stop a motor surely with an inexpensive configuration on the basis of a trip signal from an inverter. <P>SOLUTION: A motor-driven controller 100 is provided with a drive stop circuit 4 interposed between a microcomputer 1 and the inverter 2. The drive stop circuit 4 is provided with a transistor 41 turned ON when the trip signal S6 is in a released state. The transistor 41 is composed so that a collector 41C is connected to a signal line of a RUN signal S5, a base 41B is connected to a signal line of the trip signal S6, and an emitter 41E is grounded. The base 41B of the transistor 41 is connected to a DC power supply VCC set to a prescribed voltage (for example, 24 V) via a pull-up resistor 42. <P>COPYRIGHT: (C)2008,JPO&INPIT |
