3068 4068 4068
Spindle position gain on servo mode/spindle synchronous control (LOW)
CTH1A=1, CTH2A=1
Unit of data : 0.01sec
-1
Valid data range : 0 to 32767
Standard setting value : 1000
These parameters set a position gain on servo mode (rigid
tapping/spindle positioning) or spindle synchronous control.
A parameter is selected according to the input signals CTH1A and
CTH2A.
NOTE
For velocity loop gain setting on spindle synchronous
control and servo mode, the common parameters
are used.

3073 4073 4073
Grid shift amount on servo mode
Unit of data : 1 pulse (=360°/4096)
Valid data range : 0 to 4095
Standard setting value : 0
This parameter is used to shift the reference position on servo mode
(rigid tapping/spindle positioning).
The reference position of the spindle is shifted in the CCW direction
by the specified number of pulses.

3074 4074 4074
Reference position return speed on servo mode
Unit of data : 1min
-1
Valid data range : 0 to 32767
Standard setting value : 0
To perform a reference position return operation, set a reference
position return speed in this parameter.

3085 4085 4085
Motor voltage on servo mode/spindle synchronous control
Unit of data : 1%
Valid data range : 0 to 100
Standard setting value : 60
These parameters set a motor voltage on rigid tapping. Usually, set 60.
