Suppress overshoots for jerk time > 0

Description
Defines whether an overshoot that can occur when calculating the setpoint curve is suppressed.
If the drive accelerates or decelerates with a jerk time > 0 and the drive function is switched or the speed setpoint or profile values are changed, the drive can use the new active speed setpoint and the profile limits to calculate a setpoint curve that does not end at the valid speed setpoint but instead generates an overshoot. The overshoot ensures that the acceleration is correctly reduced via the specified jerk.
The parameter is used in the following drive functions:
- FCB 02 Stop default
- FCB 05 Speed control
- FCB 13 Stop at application limits
- FCB 14 Emergency stop
- FCB 26 Stop at user-defined limits
The following settings are possible:
Setting | Meaning |
|---|---|
1 (yes) | The stop drive functions continuously calculate whether it is possible to stop without overshoot using the starting values of the speed setpoint and position setpoint as well as the defined profile values of the deceleration and jerk time. If necessary, the parameterized jerk time is reduced to such an extent that the target can be reached without overshoot. INFORMATION: The Jerk time application limit is not necessarily adhered to. When switched to the FCB 05 Speed control drive function, the profile generator starts calculating the setpoint curve with acceleration 0. |
0 (no) | The drive runs the profile that is determined by the parameterized jerk time. If an overshoot occurs, this is permitted. |
DefaultSetting
