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.

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,
