7. Application of high speed pulse
7.1 high speed pulse output
Coolmay CX3G default has 8 channels high speed pulse, Y0-Y3 each 100KHz,
Y4-Y7 each 10KHz,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.
For example, target speed = 50000, current speed = 20000, acceleration time 100
(ms), maximum speed = 100,000, T = 30 ms.
CX3G: 8 channels of pulse, the last 4 channels of acceleration and deceleration =
D8148, the maximum speed is D8146, D8147.
PLSY, ZRN, PLSV, DRVI, DRVA, DVIT, DSZR, only Y0-Y3 supports DVIT (interrupt
positioning), DSZR (original return with DOG search) instructions.
