P: Sets the decelerated feedrate.
Setting unit: 1 = 1 mm/min or 0.1 inch/min
L: Sets the deceleration distance in the tangential direction
Setting unit: 1 = 0.001 mm or 0.0001 inch
Q: Sets the arc tolerance
Setting unit 1 = 0.001 mm or 0.0001 inch
Setting range: 0 to 32767
If address P, L, and/or Q is not specified, the values set for the following parameters are
used:
Decelerated feedrate . . . . . pm0860, pm0862
Deceleration distance . . . . pm0861, pm0863, pm2585
Arc tolerance . . . . . . . . . . . pm0416, pm0417
(b) Corner feedrate designation mode cancel command (G108)
The G108 command must be specified in a block without other commands.
1. The setting ranges for P and L are the same as applied for normal F commands and axis
commands.
2. The Q command becomes invalid when the NC is reset either by reset operation or a com-
mand in a program.
3. When the NC is reset, it is placed in the G108 mode.
4. The values set for P and L are displayed at the lower area of command value displayscreen
in the [RUN] process. The display is blank while in the G108 mode.
(2) Operations
• In the G01 mode
Axis movement specified in a block is divided into three sections, including the accel-
eration section and the deceleration section.
