6.2.5 Acceleration control (G130/G131)
These functions allow to change the acceleration and deceleration of the axes and spindles.
Programming
The functions related to acceleration control are:
G130 Percentage of acceleration to be applied per axis or spindle.
G131 Percentage of acceleration to be applied, global.
G130
Percentage of acceleration to be applied per axis or spindle.
The percentage of acceleration to be applied per axis or spindle is set by G130 followed by
the axes and spindles together with the percentage to be applied to each of them.
The acceleration values to be applied must be integers (not decimals).
G131
Percentage of acceleration to be applied, global
The percentage of acceleration to be applied to all the axes and spindles is set by G131
followed by the new acceleration value to be applied.
The acceleration values to be applied must be integers (not decimals).
When added to a motion block, the new values will be assumed before executing the move.
Considerations
The #SLOPE instruction determines the influence of the values defined with these values.
• In rapid positioning (G00)
• In the acceleration or deceleration stage.
• In the jerk of the acceleration or deceleration stages.
The programmed percentages are absolute, in other words, programming a 50% twice
means that 50% will be applied, not 25%.
a
0
: Nominal acceleration, set by the machine manufacturer.
a
P
: Acceleration to be applied, set by the operator.
