Unit of data : 0.01sec
-1
Valid data range : 0 to 32767
Standard setting : 3000
These parameters specify the position gains used on Cs contouring
control mode.
A parameter is selected by the input signals CTH1A and CTH2A.

Speed for return to reference position on Cs contouring control mode/servo
mode
Unit of data : 1min
-1
Valid data range : 0 to 32767
Standard setting : 0
• When 0 is set
The value set in No. 4021 (maximum spindle speed) is used as a
reference position return speed on Cs contouring control.
• When a value other than 0 is set
The value set in this parameter is used as a reference position
return speed on Cs contouring control.
NOTE
An overshoot can occur at reference position return
time for a cause such as an excessively high
reference position return speed by setting the
parameter No. 4021 (maximum spindle speed on Cs
contouring control mode). In this case, set this
parameter.

Motor voltage setting on Cs contouring control
Unit of data : 1%
Valid data range : 0 to 100
Standard setting : 100
Set the motor voltage to "100", when Cs contouring control is in
operation.
