A3.33
Rigid tapping speed loop proportional
gain
Set the analog/pulse rigid tapping speed loop
proportional gain Kp, the higher the value, the higher
the gain, the greater the stiffness.Try to set a larger value
when the system does not produce oscillation

Rigid tapping speed loop integral time
Set the velocity integral time constant Ti of the velocity
loop when the analog/pulse rigid tapping, the smaller the
value, the greater the stiffness

A3.35
Rigid tapping position loop proportional
gain
When pulse rigid tapping is set, the position loop
proportional gain Kp is set. The higher the value is, the
faster the response to the position command will be,
and the higher the stiffness will be. When the value is too
large, it is easy to cause vibration.The smaller the value,
the slower the response and the larger the following error
