Application 2: knit-weaving machine (continuous loop mode)
The machine principle: Control the inverter via PLC, thereby control the motor. Meantime,
via the feedback signal from encoder, control the knit-weaving machine and the precise
position.
Pulse frequency f
Below is PLC program: Y2 represents forward output signal; Y3 represents reverse output
signal; Y4 represents output signal of speed 1; HSC2: Back-forth times accumulation counter;
HSC0: AB phase HSC;
HSC0=K90000+(K-75000)
HSC0=K75000+K15000
I2000
HSC0=K0+K75000
