PB03 TFBGN Torque feedback loop gain
This is used to set a torque feedback loop gain in the continuous operation to torque control
mode.
Decreasing the setting value will also decrease a collision load during continuous operation to
torque control mode.
Setting a value less than 6 rad/s will be 6 rad/s.
PB04 FFC Feed forward gain
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 1 s or more as the acceleration time constant
up to the rated speed.
