Handwheel pulse function
The handwheel pulse generator is commonly known as electronic handwheel and handwheel. It is mainly used for the setting of the teaching CNC machine work origin in CNC machine tools, manual stepping fine adjustment, and interruption insertion during processing. Widely used in CNC engraving and milling machines, CNC milling machines, CNC lathes, machining centers, CNC wire cutting machine tools, CNC EDM machine tools, printing equipment, textile machinery and other fields.
Coolmay QM3G series PLC supports the function of handwheel (only supports servo motors, not stepper motors). With the cooperation of QM3G PLC, the handwheel is used to control the rotation of the motor, which can realize the rotation of the handwheel by one pulse and the motor also rotates correspondingly number of pulses.

High speed pulse output
Coolmay QM3G series plc default has 8 channels high speed pulse, Y0-Y3 each 200KHz, Y4-Y7 each 100KHz (Y4-Y7 total should not be over 200KHz),variable speed supported, the initial/final speed of start/stop is 0, diagram as below: (take accelerate and decelerate time D8148 as an example).
Acceleration/deceleration time T calculation=
(target speed-current speed)*acceleration/deceleration time÷maximum speed.
