Motor roll control device and motor roll control manner

摘要

PURPOSE:To detect the abnormal operation state of a motor, and to avoid the abnormal operation by a simple constitution by comparing the count number of a control round frequency of all control systems and a limit value set in advance. CONSTITUTION:The controller is provided with an arithmetic part 3 for controlling a prescribed number of driving means 2 for rotating and stopping each motor 6, and an external control part 4 for rotating and stopping the motor 6 by the count number of a control round frequency of all control systems and a detection state of a sensor 5, and also, discriminating an abnormal operation by comparing the count number and a limit value set in advance and stopping the motor 6. That is, it is a control system by which a processing of all control systems does not become a minute loop, and by comparing the count number of the control round frequency and the limit value set in advance without measuring the time by a timer, etc., whether such an abnormal operation as an overrun exists or not is discriminated. In such a way, in the case of an abnormal. operation, overheating of the motor and damage of a motion part are avoided.
