4 ADVANCED SYNCHRONOUS CONTROL
4.8 Phase Compensation Function

Setting example
When the axis 1 is synchronized with a synchronous encoder axis via the servo amplifier, the phase compensation advance
time is set as follows.
(When the model is MR-J5-G, the operation cycle is 2.00[ms], and the model loop gain of the axis 1 is 80)
When overshoot or undershoot occurs during acceleration/deceleration, set a longer time for the phase compensation time
constant.
