p1675 Current setpoint filter 4
numerator natural fre-
quency
0.5 16000.0 1000.0 Hz Float IM T, U
Description: Sets the numerator natural frequency for current setpoint filter 4 (general filter).
Dependency: Current setpoint filter 4 is activated via p1656.3 and parameterized via p1673 ... p1675.
p1676 Current setpoint filter 4
numerator damping
0.000 10.000 0.010 - Float IM T, U
Description: Sets the numerator damping for current setpoint filter 4.
Dependency: Current setpoint filter 4 is activated via p1656.3 and parameterized via p1673 ... p1675.
p2153 Speed actual value filter
time constant
0 1000000 0 ms Float IM T, U
Description:
Sets the time constant of the PT1 element to smooth the speed/velocity actual value.
The smoothed actual speed/velocity is compare
d with the threshold values and is only used for messages and
signals.

Description: Sets the speed threshold value for the signal that indicates the axis is stationary.
p2162 * Hysteresis speed n_act >
n_max
0.00 60000.00 0.00 rpm Float IM T, U
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 be increased, but its value must not be greater than the value calculated by the formula be-
low when the motor maximum speed is sufficiently greater than the maximum speed p1082.
p2162 ≤ 1.05 × motor maximum speed - maximum speed (p1082)
The range of the parameter is different when connect with different motors.

p2525 LR encoder adjustment
offset
0 429496729

0 LU U32 IM T
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
0.00 1000.00 0.00 ms Float IM T, U
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.
