PB42 SBW
(▲)
Synchronous control bandwidth:
If you are unsure about PB39~PB41 setting, set
the value of synchronous control bandwidth
instead so that the value corresponds to
PB39~PB41.
When the deviation between the synchronous
control bandwidth and the servo bandwidth is
greater, the synchronous following will be better.
But when speed loop bandwidth + synchronous
control bandwidth > system allowable bandwidth ,
it may cause resonance of system.
Note: when increasing the speed loop bandwidth
and synchronous control bandwidth, PB03
response should faster than them.

PB43 SVL Synchronous speed error low-pass filter:
When the synchronous control is affected by low
resolution, meaning that noise (less sharp and
rough sound) is generated, you can use low-pass
filter to suppress the noise. This filter must be
faster than the synchronous control bandwidth.

PB44 PPD Position loop compensation
Increasing this gain value will improve the
