5281 Position control loop gain of spindle and tapping axis in rigid tapping (First gear)
5282 Position control loop gain of spindle and tapping axis in rigid tapping (Second gear)
5283 Position control loop gain of spindle and tapping axis in rigid tapping (Third gear)
5284 Position control loop gain of spindle an tapping axis in rigid tapping (Fourth gear)

[Valid data range] 1 to 9999
These parameters set the position control loop gain of a spindle and
tapping axis for every gear in rigid tapping.
NOTE
To set the loop gain for every gear, set parameter No. 5280
to “0”.
5291 Spindle loop gain multiplier in the rigid tapping mode (for gear 1)
5292 Spindle loop gain multiplier in the rigid tapping mode (for gear 2)
5293 Spindle loop gain multiplier in the rigid tapping mode (for gear 3)
5294 Spindle loop gain multioplier in the rigid tapping mode (for gear4)

Set the spindle loop gain multipliers for gears 1 to 4 in the rigid tapping
mode. The thread precision depends on the multipliers. Find the most
appropriate multipliers and 1OOP gain by conducting the cutting test.
NOTE
These parameters are used for analog spindles.
Loop gain multiplier = 2048 a 1000
where;
E: Voltage in the velocity command at 1000 min

L: Rotation angle of the spindle per one rotation of the
spindle motor
