G132 | Axis-specific weighting of ramp time |

<axis_name><expr> | Weighting for specific axes in [%] |

G133 | Axis group-specific weighting of ramp time with G01, G02, G03 |

<expr> | weighting for all axes in [%] |

G134 | Axis group-specific weighting of geometrical ramp time |

<expr> | weighting for all axes in [%] |

G233 | Axis group-specific weighting of ramp time with G0 |

<expr> | weighting for all axes in [%] |

The G132/G133/G233 functions can change the ramp time of axis acceleration with a non-linear slope [2]-1. (If the slope is linear, the acceleration curve is step-shaped (see figure in Section Jerk-limiting slope)

The G134 function can change the geometrical ramp time of a non-linear slope (P-AXIS-00199).

These ramp times can be influenced by a percentage change in the associated default ramp times.

When programming with G132/G133/G134/G233 all axes which are not programmed or not yet programmed are set to 100%. Every additional selection of these functions, irrespective of previous programming, refers to 100%. This means that geometrical data processing always weights default values with the percentage value. Therefore, 50% programmed twice in succession means the setting is made to 50% and not to 25%.

## Attention

After an axis exchange, the G132 weighting factors are reset to 100% for all the axes involved.

## Notice

The ramp time weighting has **no** effect with single axis motions, such as homing, manual mode and independent axes.

## Programing Example

Ramp time weighting (G132/G133/G134/G233)

N10 G132 X200 | (Axis-specific ramp time weighting) (Ramp time of X axis is increased by 200%.) |

N20 G01 F1000 X100 | (Linear interpolation) |

N30 G132 Y50 | (Ramp time of Y axis is decreased by 50%) (Ramp time of X axis remains at 200%) |

N40 Y100 | (Linear interpolation) |

N50 G133 = 100 | (Axis group-specific ramp time weighting) (G01,G02,G03 ramp times of all axes to 100%) |

N60 G134 = 50 | (Axis group-specific ramp time weighting) (Geometric ramp time of all axes to 50%) |

: | |

N70 G233 = 80 | (Axis group-specific ramp time weighting) (G00 ramp times of all axes to 80%) |

N80 G00 X200 | (Rapid traverse) |

| |

N50 G133 = 100 X10 Y20 | (With G133/G233 in the same block, axis also) (can also be programmed.) |

N60 G134 = 50 X10 Y20 | (With G134 in the same block, axis positions) (can also be programmed.) |

The figure below shows the influence of G134 on acceleration perpendicular to the path (centrifugal acceleration a1--> a2) with increasing feed (v1 --> v2) during circular motion (P1 --> P2).

If the change in centrifugal acceleration is reduced by increasing the G134 ramp time, acceleration is smoother and target acceleration a2 is not reached until point P3.
