15.1.20 Acceleration control
The acceleration and the jerk (variation of acceleration) applied on the
movements are set by machine parameters. However, those values
may be changed from the program using functions G130, G131, G132
and G133.
The #SLOPE instruction sets the influence of the values defined by
these functions on how the acceleration will behave.
#SLOPE It sets the behavior of the acceleration
This instruction sets the influence of the values defined with functions
G130-G133 in the behavior of the acceleration.
The programming format is:
#SLOPE [<type>,<jerk>,<accel>,<move>]
It is not necessary to program all the parameters. The values that each
parameter may take are the following.
• The <type> parameter determines the type of acceleration.
By default, it assumes a value of ·0·.
The optional <jerk> parameter sets the influence of the Jerk
defined with functions G132 and G133. It will only be taken into
account in trapezoidal and square-sine type acceleration.
By default, it assumes a value of ·0·.
Parameter Meaning
<type> Acceleration type.
<jerk> Optional. It sets the influence of the jerk.
<accel> Optional. It sets the influence of the acceleration.
<mov> Optional. It affects the movements in G00.
#SLOPE [1,1,0,0]
#SLOPE [1]
#SLOPE [2,,,1]
Value Meaning
0 Linear acceleration.
1 Trapezoidal acceleration.
2 Square sine (bell shaped) acceleration.
Value Meaning
0 It modifies the jerk of the acceleration and
deceleration stage.
1 It modifies the jerk of the acceleration stage.
2 It modifies the jerk of the deceleration stage.
