16 Machine Parameters
#2112 Blf motor inertia
Set the motor inertia for quadrant protrusion compensation.
Refer to the servo manual and input the value appropriate for the motor.
---Setting range---
1 to 32000 (10
#2113 Blf visc friction
Set the viscous friction for quadrant protrusion compensation.
After setting the other parameters to the appropriate values, monitor the machine end and gradually adjust
the value.
If this parameter setting is small, a recess will form on the inner side of the circle, and if large, a protrusion
will form on the outer side of the circle. When the value is appropriate, a spike-shaped quadrant protrusion
will form based on normal step-shaped backlash.
---Setting range---
1 to 32767 (1/16 Nm/(rad/s))
#2114 Blf fwdg
Set the feed forward gain for quadrant protrusion compensation.
After setting the other parameters to the appropriate values, monitor the machine end and gradually adjust
the value.
If this parameter setting is small, a large quadrant protrusion will form, and if large, a recess will form on the
inner side of the circle.
---Setting range---
0 to 1000 (%)
#2115 Blf motor stl trq
Set the motor rated current for quadrant protrusion compensation.
Refer to the servo manual and input the value appropriate for the motor.
---Setting range---
1 to 16000 (1/256 Nm)
(PR) #2118 SscDrSel
Select which door group of the speed monitoring the spindle belongs to.
0000: Door 1 group.
0001: Door 1 group.
0002: Door 2 group.
0003: Door 1 and 2 group.
The speed monitoring will not be executed when "#2313 SV113 SSF8/BitF" is OFF regardless of this param-
eter.
The selected door group must be set when setting the synchronous control.
The spindle/C axis control enables the door selection in "#3071 SscDrSelSp" for the corresponding spindle.
#2121 vbacklash valid
Select whether the variable backlash is to be disabled/enabled/continuous, or variable backlash II enabled.
0: Disable
1: Enable
2: Continuous
3: Enable variable backlash II
("#2011 G0back" and "#2012 G1back" will not work unless "0: Disable" is selected. )
#2122 G0vback+
Set the compensation amount for the range of each position during rapid traverse.
(+: B1, =: B2, -: B3 on the compensation amount table)
