5.8 Encoder ABZ phase frequency division output 
The servo driver outputs the differential signal through the frequency division output circuit. It can 
provide position signal for the control of the upper computer or pulse signal for the driven servo, so as 
to realize the follow-up control of the master-slave shaft.

3. Encoder feedback pulse number per turn 
Set the number of feedback pulses per turn of encoder (low-order position) 
Set the number of feedback pulses per turn of encoder (high-order position) 
Note: 
(1) Output pulses per turn: P0-19 * 10000 + P0-18. It can be any positive integer. 
(2)  Encoder  feedback  will  be  output  from  CN0  port  (hardware  version  3131  and  earlier  encoder 
feedback output at CN1 port). It is recommended that the lower computer accept pulse with AB phase 
counter. 
If AB phase counting is adopted, the counting value of motor rotation for one turn is 4 times of the 
set pulse number per turn of encoder (P0-18 + P0-19 * 10000). 
(3) The pulse output frequency of each phase shall not exceed 1MHz, and the number of pulses per 
cycle can be set in cooperation with the z-phase pulse estimation formula. 
Example: Assume the actual speed of motor is 3000rpm,
