Unit: ms

Settings:
When the stiffness of the mechanical system between full- and half-closed loops is insufficient, set the
proper time constant to enhance the stability of the system. In other words, temporarily create the
half-closed loop effect, and after stabilizing, the full-closed loop effect is created. When the stiffness is
sufficient, set to bypass.
Set the value to 0 to disable the low-pass filter (bypass) function.
If the stiffness of the mechanical system is high, decrease the value of P1.075, or set the value to 0 to
disable. If the stiffness of the mechanical system is low, increase the value of P1.075.

Default: 5500
Unit: rpm
Format: DEC
Settings:
Input the actual maximum speed of the motor as the reference value to activate the smoothing function.
When you set the value to 0, the smoothing function is disabled.
