Torque
command
filter
① It is used to limit the current command frequency band and
suppress the resonance caused by torque (the motor produces
sharp vibration noise) so that current response becomes
smooth.
② Reduce the parameter if the motor makes sharp vibration
noise;
③
The smaller the setting is, the lower the cut-off frequency, the
better the filtering effect and the lower the noise produced by
the motor will be. In case of high load inertia, it is possible to
appropriately reduce the setting. Excessively small setting may
slow down response and cause instability.
④
The bigger the setting is, the higher the cut-off frequency and
the faster the response will be. It is possible to appropriately to
increase the setting if relatively high mechanical rigidity is
required.

Low pass
filter for
speed
detection
①
The parameter is used to set the characteristics of the
low-pass filter for speed detection.
② The smaller the setting is, the lower the cut-off frequency, the
better the filtering effect and the lower the noise produced by
the motor will be. In case of high load inertia, it is possible to
appropriately reduce the setting. Excessively small setting may
slow down response, increase speed fluctuation and cause
disturbance.
③
The bigger the setting is, the higher the cut-off frequency and
the faster the response will be. It is possible to appropriately to
increase the setting if relatively high mechanical rigidity is
required.

Proportional
gain of
position
①
The parameter is used to set the proportional gain of the
position ring adjuster.
②
The gain and rigidity increase with the setting. Under the same
frequency command pulse condition, the position lag becomes
less but excessive setting may cause disturbance or
overshooting.
③
The setting of the parameter depends on the version and load
of the servo drive system.
