P20 pulse frequency division output?

1.Industrial Background
P20 dual-axis model. Axis A uses the pulse frequency division output function to send the signal to axis B, thereby achieving synchronous operation of the two axes.
2.Wiring
CN2 terminal
3.Parameter settings
The DO_2, DO_3, DO_4 channel function selection function code under the P20 is 143 OZ/A/B (Z phase pulse/A phase pulse/B phase collision).
These three channels correspond to the Z phase and A phase of the pulse output respectively,B phase!
A axis
| Parameter | Description | Set Value | Remarks |
| P00-21 | Pulse frequency division output direction | 0/1 | 0：CW is forward direction (A is ahead of B) 1：CCW is forward direction (A is ahead of B) |
| P00-22 | The number of output pulses per turn of motor | 2500 | 0 to 2500 |
| P06-28 | DO_2 channel function selection | 143 | Z phase pulse |
| P06-30 | DO_3 channel function selection | 143 | A phase pulse |
| P06-32 | DO_4 channel function selection | 143 | B phase collision |
B axis
| Parameter | Description | Set Value | Remarks |
| P00-12 | Pulse frequency division output direction | 0/1 | 2: A, B phase quadrature pulse (4 times frequency) |
