Single phase:
at most 6 channels, max frequency is 60KHz
AB(Z) phase:
2 times frequency: 2 channels 60KHz+1 way 10KHz;
4 times frequency: 2 channels 24KHz; M8198 is C251 4 times frequency signal;M8199 is C253 4 times
frequency signal.
* High speed input C254:
When M8396=0, the original C254 is AB phase corresponded to X3 X4.
When M8396=1, C254 changes to AB phase corresponded to X6 X7.
2.10.Application of high speed pulse
2.10.1 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).
