Par. No. Name
p2162 * Hysteresis speed n_act >
n_max
Description: Sets the hysteresis speed (bandwidth) for the signal "n_act > n_max".
Note:
For a negative speed limit, the hysteresis is effective below the limit value and for a positive speed limit above
the limit value.
If significant overshoot occurs in the maximum speed range (for example, due to load shedding), you are
advised to increase the dynamic response of the speed controller (if possible). If this is insufficient, the hyste-
resis p2162 can only be increased by more than 10% of the rated speed when the maximum speed of the
motor is sufficiently greater than the speed limit p1082.
The range of the parameter is different when connect with different motors.
p2525 LR encoder adjustment
offset
Description: For the absolute encoder adjustment, a drive determines the position offset.
Note: The position offset is only relevant for absolute encoders. The drive determines it when making the
adjustment and the user should not change it.
p2533 LR position setpoint filter
time constant
Description: Sets the time constant for the position setpoint filter (PT1).
Note: The effective Kv factor (position loop gain) is reduced with the filter.
This allows a softer control behavior with improved tolerance with respect to noise/disturbances.
Applications:
- Reduces the pre-control dynamic response.
- Jerk limiting.
p2542 * LR standstill window
Description: Sets the standstill window for the standstill monitoring function.
After the standstill monitoring time expires, it is cyclically checked whether the difference between the setpoint
and actual position is located within the standstill window and, if required, an appropriate fault is output.
Value = 0: The standstill monitoring is deactivated.
Dependency: Refer to: p2543, p2544, and F07450
Note: The following applies for the setting of the standstill and positioning window:
Standstill window (p2542) ≥ positioning window (p2544)
p2543 * LR standstill monitoring
time
Description: Sets the standstill monitoring time for the standstill monitoring function.
After the standstill monitoring time expires, it is cyclically checked whether the difference between the setpoint
and actual position is located within the standstill window and, if required, an appropriate fault is output.
Dependency: Refer to: p2542, p2545, and F07450
Note: The following applies for the setting of the standstill and positioning monitoring time:
Standstill monitoring time (p2543) ≤ positioning monitoring time (p2545)
