Parameters
10.2 Parameter list
Par. No. Name
p1423 Speed setpoint filter 2
denominator natural fre-
quency
Description: Sets the denominator natural frequency for speed setpoint filter 2 (PT2, general filter).
Dependency: Refer to p1414, p1421
Note: This parameter is only effective if the speed filter is parameterized as a PT2 low pass or as general
filter.
The filter is only effective if the natural frequency is less than half of the sampling frequency.
p1424 Speed setpoint filter 2
denominator damping
Description: Sets the denominator damping for speed setpoint filter 2 (PT2, general filter).
Dependency: Refer to p1414, p1421
Note: This parameter is only effective if the speed filter is parameterized as a PT2 low pass or as general
filter.
p1425 Speed setpoint filter 2
numerator natural fre-
quency
Description: Sets the numerator natural frequency for speed setpoint filter 2 (general filter).
Dependency: Refer to p1414, p1421
Note: This parameter is only effective if the speed filter is set as a general filter.
The filter is only effective if the natural frequency is less than half of the sampling frequency.
p1426 Speed setpoint filter 2
numerator damping
Description: Sets the numerator damping for speed setpoint filter 2 (general filter).
Dependency: Refer to p1414, p1421
Note: This parameter is only effective if the speed filter is set as a general filter.
p1441 Actual speed smoothing
time
Description: Sets the smoothing time constant (PT1) for the speed actual value.
Note: The speed actual value should be smoothed for increment encoders with a low pulse number.
After this parameter has been changed, we recommend that the speed controller is adapted and/or the speed
controller settings checked Kp (p29120) and Tn (p29121).
p1520 * Torque limit upper
Description: Sets the fixed upper torque limit.
Danger: Negative values when setting the upper torque limit (p1520 < 0) can result in the motor accelerating
in an uncontrollable fashion.
Notice: The maximum value depends on the maximum torque of the connected motor.
p1521 * Torque limit lower
Description: Sets the fixed lower torque limit.
Danger: Positive values when setting the lower torque limit (p1521 > 0) can result in the motor accelerating in
an uncontrollable fashion.
Notice: The maximum value depends on the maximum torque of the connected motor.
