Two methods of controlling the forward and reverse rotation of servo motor by Mitsubishi plc

Mitsubishi plc fx3u-64mt/es-a controls the forward and reverse rotation of servo motor.

Mitsubishi plc fx3u-64mt/es-a can control three servos. If you want to control four servos, you must add a positioning module or use two adapters to solve the problem of controlling four servos. You only need two servos to achieve positive and negative rotation. First of all, ontology is enough. Open collector output mode, generally y0 to y3 can be used as the output points of sending pulses, and the direction output points can be arbitrarily selected.

The servo positioning completion signal is led out from the servo mechanism, so that the two servo mechanisms can rotate forward through absolute positioning or relative positioning, and then rotate reversely.

Two methods to control the forward and reverse rotation of motor;

1, send out a single pulse, and then use whether there is a signal at another point (0, 1) to indicate forward transmission and reverse transmission.

2. Send out double pulses, and the electrical angle of the two pulses leading or lagging by 90 degrees indicates that the motor is rotating forward or backward.

The second method is often used for positive and negative data of servo.
