Option Name
Description
[6]
Poly 5'order Connects the CAM table points with a 5
th
order polynomial. At least 3 consecutive CAM table points of
this type are required to use this selection.
[8]
Sine
Connects the CAM table points with a full sine wave.
[9]
Cosine
Connects the CAM table points with a full cosine wave.
[10]
End
Always select this option for the last point of the curve.
Parameter 3-39 CAM Follower Gain
Table 221: Parameter 3-39 CAM Follower Gain
3-39 CAM Follower Gain
Default value: 100.0
Parameter type: Range, 0.0 - 500.0%
Setup: All setups
Conversion index: -1
Data type: Uint16
Change during operation: True
N O T I C E
This parameter is only available with software version 48.XX.
The follower table is multiplied by this gain which can be adjusted while running.
5.4.5 3-4* Ramp 1
For each of the 4 ramps (
parameter groups 3-4* Ramp 1
,
3-5* Ramp 2
,
3-6* Ramp 3
, and
3-7* Ramp 4
) configure the ramp parameters:

Illustration 51: Linear Ramping Times
If S-ramps are selected, set the level of non-linear jerk compensation required. Set jerk compensation by defining the proportion of
ramp-up and ramp-down times where acceleration and deceleration are variable (that is, increasing or decreasing). The S-ramp ac-
celeration and deceleration settings are defined as a percentage of the actual ramp time.
