The constant of the torque disturbance compensating (Acceleration feedback
gain)
Unit of data :
Valid data range : 0 to 32767
Standard setting : 0
This parameter specifies the constant for compensating for a
disturbance torque on Cs contouring control mode.
NOTE
By setting this parameter, stability in cutting can be
improved.
In this parameter, set a value from 500 to 2000.
Do not set a value exceeding 4000.

Velocity detection filter time constant (on Cs contouring control)
Unit of data : 0.1ms
Valid data range : 0 to 10000
Standard setting value : 0
This parameter sets a filter time constant for the velocity feedback
signal on Cs contouring control. Usually, set 0.

Grid shift amount on Cs contouring control
Unit of data : 1 pulse unit (=0.001°) (0.0001° when bit 0 (CS360M) of parameter No.
4005 is set to 1)
Valid data range : -360000 to +360000
(When parameter No. 4005 #0 (CS360M) is 1, -3,600,000 to
+3,600,000)
Standard setting value : 0
Use this parameter to shift the machine reference position on Cs
contouring control.
The machine reference position of the spindle shifts by the set number
of pulses in the CCW direction.
