Abstract

The invention discloses a programmable motor control method. In the method, an input state quantity module, a logical programming module, a control functional module, a delay timer and an output module are connected in sequence; the input state quantity module is used for providing various control signal sources; different input state quantities are selected according to control ways needing to be realized; a required logical relation is set by programming; judgment is made according to a predetermined control function logical relation; and the output module is used for executing a resulting action after set time of the delay timer, so that a selected control function is realized. According to the method, a plurality of (16) motor control ways can be realized selectively through limited state quantity inputs (8), and the 16 types of control ways basically meet all common control requirements of a low-voltage motor, so that the programmable motor control method is suitable for different industries and different working conditions.

Description

technical field [0001] The invention relates to a programmable motor control method, which relates to the technical field of motor protection and monitoring, in particular to the technical field of protection, monitoring and control of microcomputer-based low-voltage motors. Background technique [0002] Due to the different industries and working conditions of the motor, different motor control methods and starting methods have been formed. This problem exists even in a substation. In order to adapt to various control methods, many different secondary motors have been produced. Each control mode corresponds to a secondary control circuit. Since the control circuit is mostly composed of separate components such as time relays, the control wiring is complicated, the control accuracy is low, the stability and safety are poor, the construction is difficult, and the maintenance cost in the later period High, can not meet the requirements of modern, automated production. Conten...
