1783
Allowable speed difference for the speed difference based corner
deceleration function (linear acceleration/deceleration before interpolation)
[Data type] Word axis
[Unit of data, valid data range]
Valid data range
Increment system Unit of data
IS-A, IS-B IS-C
Millimeter machine 1 mm/min 6 to 15000 6 to 12000
Inch machine 0.1 inch/min 6 to 6000 6 to 4800
Rotation axis 1 deg/min 6 to 15000 6 to 12000
A separate allowable feedrate difference can be set for each axis. The
allowable feedrate difference is set for each axis with this parameter.
Among the axes that exceed the specified allowable feedrate
difference, the axis with the greatest ratio of the actual feedrate
difference to the allowable feedrate difference is used as the reference
to calculate the reduced feedrate at the corner.
1784
Speed when overtravel alarm has generated during acceleration/deceleration
before interpolation
[Data type] Word
[Unit of data, valid data range]
Valid data range
Increment system Unit of data
IS-A, IS-B IS-C
Millimeter machine 1 mm/min 6 to 15000 6 to 12000
Inch machine 0.1 inch/min 6 to 6000 6 to 4800
Rotation axis 1 deg/min 6 to 15000 6 to 12000
Deceleration is started beforehand to reach the feedrate set in the
parameter when an overtravel alarm is issued (when a limit is reached)
during linear acceleration/deceleration before interpolation. By
using this parameter, the overrun distance that occurs when an
overtravel alarm is output can be reduced.
This setting can be applied also to rapid traverse blocks by setting bit
0 (OTR) of parameter No.7057. (M series)
NOTE
1 When 0 is set in this parameter, the control
described above is not exercised.
2 Use type-B linear acceleration/deceleration before
interpolation (by setting bit 0 (FWB) of parameter
No.1602 to 1).
3 The control described above is applicable only to
stored stroke check 1.
4 The control described above is performed for the
axes specified in the current block and next block.
By setting bit 5 (ODA) of parameter No. 7055, the
control can be performed just for the axis specified
in the current block.
