6.2.6 Jerk control (G132/G133)
The jerk of axes and spindles may be modified with these functions.
Programming
The functions associated with jerk control are:
G132 Percentage of jerk to be applied per axis or spindle.
G133 Percentage of jerk to be applied, global.
G132
Percentage of jerk to be applied per axis or spindle.
The percentage of jerk to be applied per axis or spindle is set by G132 followed by the axes
and spindles together with the new jerk to be applied to each of them.
The jerk values to be applied must be integers (not decimals).
G133
Percentage of jerk to be applied, global
The percentage of jerk to be applied to all the axes and spindles is set by G133 followed by
the new jerk value to be applied.
The jerk values to be applied must be integers (not decimals).
When added to a motion block, the new jerk values will be assumed before executing the
move.
Considerations
The #SLOPE instruction determines whether the new percentages are to be applied or not
on to rapid traverse movements (G00).
The programmed percentages are absolute, in other words, programming a 50% twice
means that 50% will be applied, not 25%.
Properties of the functions
Functions G132 and G133 are modal and incompatible with each other.
On power-up, after an M02, M30, EMERGENCY or a RESET, the CNC restores 100% of
jerk for all the axes and spindles.
G00 X0 Y0
G01 X100 Y100 F600
G132 X20 Y50 (Jerk on the X axis = 20%)
(Jerk on the Y axis = 50%)
G01 X0
G01 Y0
G133 100 X50 Y80 (Restore 100% of jerk on all the axes. Movement to point X=50 Y=80)
