Parameter 3-39 CAM Follower Gain
Table 221: Parameter 3-39 CAM Follower Gain
3-39 CAM Follower Gain
Default value: 100.0
Conversion index: -1
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:
• Ramp type
• Ramping times (duration of acceleration and deceleration)
• Level of jerk compensation for S-ramps
Start by setting the linear ramping times corresponding to

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.
