Maximum speed on Cs contouring control mode
Unit of data : 1min
-1
Valid data range : 0 to 32767
Standard setting : 100
This parameter specifies the maximum speed of a spindle operating on
Cs contouring control mode.
When 0 is specified as the parameter for the feedrate for reference
position return on Cs contouring control mode (parameter No. 4074),
reference position return is performed at the speed specified as the
maximum speed in this parameter.

Feed-forward coefficient
Unit of data : 1%
Valid data range : 0 to 100
Standard setting : 0
Set the feed-forward coefficient when feed-forward control is
executed on Cs contouring control.

Velocity loop feed-forward coefficient
Unit of data :
Valid data range : 0 to 32767
Standard setting : 0
Set a velocity loop feed-forward coefficient when feed-forward
control is executed on Cs contouring control. Use the following
expression to determine a value to be set:
[spindle inertia + rotor inertia](kg⋅m

Velocity loop proportional gain on Cs contouring control (LOW) CTH1A=1
Unit of data :
Valid data range : 0 to 32767
Standard setting : 30
These parameters specify the proportional gains of the velocity loop
on Cs contouring control mode.
When the input signal CTH1A = 0, (HIGH) is selected. When the
input signal CTH1A = 1, (LOW) is selected.
