motors speed following can be enhanced and the speed error between
two motors can be reduced. However, if the value is set too big, it may
easily cause vibration and noise It is suggested to set the value the
same as P2-06.

of synchronous control value will do since the value will correspond to
P2-54 ~ P2-56. The bigger the bandwidth of synchronous control value
is, the better the synchronous effect will be. When the bandwidth of
speed loop plus the bandwidth of synchronous control is greater than
the system's allowable bandwidth, it causes system resonance. When
increasing the bandwidth of speed loop and synchronous control, pay
special attention to the response of P2-25 which should be faster than
the setting of the both bandwidth.

noise (not a high-pitched but rough sound), low-pass filter can be used
to solve this problem. Please note that bandwidth of the synchronous
control should be set as large as possible and should larger than the
bandwidth of speed-loop.
