Note 1. Each axis: Set a value for each of the A-axis and the B-axis.
Common: Common parameters for the A-axis and the B-axis. Set same values for the A-axis and the B-axis. If different values are
set, the last set value becomes valid.
2. Valid for the A-axis and the B-axis.

PB01 FILT Adaptive tuning mode (Adaptive filter
Used to set the mode for the machine resonance suppression filter 1.
0 0 0

PB02 VRFT Vibration suppression control tuning mode (advanced vibration suppression
control)
Used to set the tuning mode for the vibration suppression control.

PB03 This parameter is not used. Do not change the value.
PB04 FFC Feed forward gain
This parameter cannot be used in the speed control mode.
Set the feed forward gain. When the setting is 100%, the droop pulses during
operation at constant speed are nearly zero. However, sudden
acceleration/deceleration will increase the overshoot. As a guideline, when the
feed forward gain setting is 100%, set 1s or more as the acceleration time
constant up to the rated speed.
