This parameter sets a servo loop gain in servo mode.
(spindle positioning, rigid tapping, etc.)
NOTE
When the spindle positioning by a serial spindle is
performed, set the position control loop gain in place of
parameter No. 4970. For which gear is used, it depends on
the clutch/gear signal (serial spindle) CTH1A, CTH1B.

IOR Resetting the system in the spindle positioning mode
0 : Does not releases the mode.
1 : Releases the mode
IDM The positioning direction for the spindle using a M code is
0 : The positive direction
1 : The negative direction
ISZ When an M code for spindle orientation is specified in spindle
positioning:
0 : The spindle rotation mode is cleared and the mode is switched to the
spindle positioning mode, and spindle orientation operation is
performed.
1 : The spindle rotation mode is cleared and the mode is switched to the
spindle positioning mode but spindle orientation operation is not
performed.
TRV Direction of rotation of spindle positioning
0 : Normal
1 : Reverse
ESI Selection of a spindle positioning specification
0 : The conventional specification is used.
1 : The extended specification is used.
