Coolmay L02 Series PLC Programming Manual
7. Application of high speed pulse
7.1. high speed pulse output
Coolmay L02 series plc default has 8 channels high speed pulse, Y0-Y3
each 100KHz, Y4-Y7 each 50KHz, 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.
L02 plc: 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 (origin return with DOG search) instructions.
