Chapter 8 Servo Parameters
2. The pulse phase compensation function is enabled only when the setting
value of parameter P1-18 is higher than 0.
3. The pulse phase compensation function is enabled only when the value of the
pulse frequency of E-Cam master axis (monitoring variable is 060 (3Ch) Pulse
number of E-Cam master axis (Incremental)) is higher than the setting value
of parameter P1-21.

When the changes of PR (or E-Cam) commands are too fast, it will cause the
vibration of the mechanical system and affect the system performance. Using
this function is able to control the acceleration (deceleration) speed not to
exceed thw limit to smooth the operation, reduce the noise and extend the
system life.
This function has different meaning than general filter function. The
traditional filter function will perform filter the commands no matter the
changes of the commands are fast or slow. This always makes the commands
be delivered with time delay and lower the efficiency of the system. This
function can help to disable the filter function when the changes of the
commands are not fast. Then, the commands can be delievered with no time
delay. The definition of this setting is the required acceleration time when the
motor runs from 0 to 3000 r/min. The required time is longer, the effect of
the filter function is better and the acceleration / deceleration will become
smoother.
