Acceleration/Deceleration is carried out so that the acceleration/deceleration time will not become longer
than this parameter's setting when the acceleration/deceleration type of rapid traverse command is constant
inclination.
Set a value smaller than "#2004 G0tL".
This parameter is enabled when "#1200 G0_acc" is constant inclination type.
This parameter is enabled only during fixed cycle if "#1253 set25 bit2" (Acceleration/Deceleration mode
change in hole drilling cycle) is enabled even if "#1200 G0_acc" is constant inclination type.
This parameter is disabled if 0 or a value larger than "#2004 G0tL" is set.
---Setting range---
0 to 4000 (ms)
Acceleration/Deceleration is carried out so that the acceleration/deceleration time will not become longer
than this parameter's setting when the acceleration/deceleration type of linear interpolation command is con-
stant inclination.
Set a value smaller than "#2007 G1tL".
This parameter is enabled when "#1201 G1_acc" is constant inclination type.
This parameter is enabled only during fixed cycle if "#1253 set25 bit2" (Acceleration/Deceleration mode
change in hole drilling cycle) is enabled even if "#1200 G0_acc" is constant inclination type.
This parameter is disabled if 0 or a value larger than "#2007 G1tL" is set.
---Setting range---
0 to 4000 (ms)
Set the changeover speed at speed normalization.
Set a value smaller than that in "#2562 VBL2 VG0".
Normally, the "#2561 VBL2 VG1" value corresponds to the cutting feedrate, the "#2562 VBL2 VG0" value to
the rapid traverse rate.
---Setting range---
1 to 1000000 (mm/min)
Set the changeover speed at speed normalization.
Set a value greater than that in "#2561 VBL2 VG1".
Normally, the "#2561 VBL2 VG1" value corresponds to the cutting feedrate, the "#2562 VBL2 VG0" value to
the rapid traverse rate.
---Setting range---
1 to 1000000 (mm/min)
Set the most plus (+) side stroke position among the three.
Set the parameters VBL2 P1 to P3 to be "VBL2 P1 > VBL2 P2 > VBL2 P3".
Normally, divide the axis's stroke by four, and set a dividing position (except for the both ends) to be a stroke
position.
---Setting range---
-99999.999 to 99999.999 (mm)
Set the middle stroke position among the three.
Set the parameters VBL2 P1 to P3 to be "VBL2 P1 > VBL2 P2 > VBL2 P3".
Normally, divide the axis's stroke by four, and set a dividing position (except for the both ends) to be a stroke
position.
---Setting range---
-99999.999 to 99999.999 (mm)
