II - 116
【#2103】 skip_t1 Skip time constant primary delay / Second-step time constant for soft
acceleration/deceleration
Set a primary-delay time constant for variable speed skip acceleration and deceleration, or
for an occasion where a skip command issues acceleration/deceleration time constant
enabled (R1).
The time constant will be enabled when C1 (cutting feed with primary delay) or C3
(exponential acceleration and linear deceleration) is selected in "#2003 smgst Acceleration
and deceleration modes". When the soft acceleration/deceleration is selected, the second-
step time constant will be used.
When set to "0", the time constant set by "#2008 G1t1" is used.
---Setting range---
0 to 5000 (ms)
【#2106】 Index unit Indexing unit
Set the indexing unit to which the rotary axis can be positioned.
---Setting range---
0 to 360 (°)
【#2109】 Rapid (H-precision) Rapid traverse rate for high-accuracy control mode
Set the rapid traverse rate for each axis in the high-accuracy control mode. "#2001 rapid"
will be used when "0" is set.
---Setting range---
0 to 1000000 (mm/min)
【#2110】 Clamp (H-precision) Cutting feed clamp speed for high-accuracy control mode
Set the cutting feed maximum speed for each axis in the high-accuracy control mode.
"#2002 clamp" will be used when "0" is set.
---Setting range---
0 to 1000000 (mm/min)
【#2111】 Blf valid Quadrant protrusion compensation valid
Set whether to enable the quadrant protrusion compensation.
0: Disable
1: Enable
If either of "#2112 Blf motor inertia", "#2115 Blf motor stl trq" or "#2113 Blf visc friction" is set
to "0", quadrant protrusion compensation will not work even if this parameter is set to "1".
【#2112】 Blf motor inertia 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 (10-6kgm2)
【#2113】 Blf visc friction Viscous 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 Compensation FF gain
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 Motor stall torque
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)
【#2118(PR) 】 SscDrSel Speed monitor Door selection
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 parameter.
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.
