Search WeChatTechnical Training Stepper motors are commonly used for positioning control, and they can control the rotation angle (which can be relative distance) through the number of pulses output by the PLC. The frequency of the pulses controls the speed of the stepper motor. For applications where high precision is not required, this method is … Read more
Search WeChatTechnical Training1 When PLC and the upper computer (or touch screen) form a monitoring system, it is often necessary to have control modes like “manual” and “automatic” on the screen (generally multiple modes can only be selected one at a time). In the program, you can use the “MOV” instruction. For example: when “manual” … Read more
