7. Servo Parameters
7.2 MDS-C1-Vx High-gain (MDS-B-Vx4 Compatible)
Set the position loop gain during the spindle
synchronous control (synchronous tapping,
synchronous control with spindle/C axis).
Set the same value as the value of the spindle
parameter, position loop gain in synchronous
control.
When performing the SHG control, set this with
SV050 (PGN2sp) and SV058 (SHGCsp).
Set this with SV049 (PGN1sp) and SV058
(SHGCsp) if you wish to perform the SHG control in
the spindle synchronous control (synchronous
tapping, synchronous control with spindle/C axis).
When not performing the SHG control, set to "0".
Set the control time constant in dual feed back.
When "0" is set, the actual value that is set is 1ms.
The higher the time constant is, the closer it gets to
the semi-closed control, so the limit of the position
loop gain is raised.
Set the non-sensitive band in the dual feedback
control.
Set to "0" as a standard.
Set the excessive error detection width when servo
ON in a special control (initial absolute position
setting, stopper control, etc.).
If "0" is set, excessive error detection won't be
performed when servo ON during a special control.
