Title:
CONTROL SYSTEM FOR INVERTER
Document Type and Number:
Japanese Patent JPS59185170
Kind Code:
A
Abstract:
PURPOSE:To enable to continue operating of an inverter by identifying the generation of a reset to a microcomputer controller for controlling the inverter, and automatically resetting the operation of the inverter only at the erroneous operating and instantaneous power interrupting time of the controller. CONSTITUTION:A motor or the like is driven by a converter 1 and an inverter 2, and the inverter 2 is controlled by a microcomputer controller 4 for controlling a memory 5. At this time a detector 7 for detecting the erroneous operation of the controller 4 and a resetter 8 connected to a detector 9 for detecting the instantaneous power interruption of a power source are operated as a pair to detect whether the generation of the reset of the controller 4 is by power source energizing time, the erroneous operation of the controller 4 or the occurrence of the instantaneous power interruption, and the automatic reenergization of the inverter 2 is enabled at the erroneous operation and instantaneous power interrupting time. Accordingly, the restarting operation by manual can be eliminated to continue the operation, thereby improving the reliability.
