9.3.3 Feedrate in incremental jog (#MPG).
This instruction allows for the configuration, for each position on the handwheel, of the
resolution of the handwheel on the specified axis. These values may be defined before or
after activating manual intervention and stay active until the end of the program or a reset.
Programming.
Program the #INCJOG statement, followed by the resolution at each jog position for the axis.
Programming format.
The programming format is the following; the arguments appear between curly brackets and
the optional ones between angle brackets.
#MPG [{resolution_1},{resolution_10},{resolution_100}] {axis}
{resolution_1}
··
{resolution_100}
Resolution position, 1 to 100 for the handwheel switch.
Units: Millimeters/pulse, inches/pulse or degrees/pulse.
{axis} Axis name.
Units: -.
#MPG [0.1, 1, 10] X
(The resolution at each handwheel switch position is as follows)
(Position 1 on the switch; 0.1 mm/turn)
(Position 10 on the switch; 1.0 mm/turn)
(Position 100 on the switch; 10 mm/turn)
This instruction sets the distance per handwheel pulse in a time period equal to the CNC’s cycle time.
If the feedrate required for this movement exceeds the maximum set by the machine manufacturer,
the feedrate will be limited to this value and the axis moving distance will be less than what has been
programmed in the instruction.
Example: If a 5 mm move is programmed and the cycle time is 4 msec, the resulting feedrate is 1250
mm/sec. If the maximum feedrate is limited to 1000 mm/s, the actual distance moved will be 4 mm.
