p1424  Speed setpoint filter 2 
0.001  10.000  0.700  -  Float  IM  T, U 
Description: Sets the denominator damping for speed setpoint filter 2 (PT2, general filter). 
 This parameter is only effective if the speed filter is parameterized as a PT2 low pass or as general 
p1425  Speed setpoint filter 2 
numerator natural fre-
0.5  16000.0  1999.0  Hz  Float  IM  T, U 
Description: Sets the numerator natural frequency for speed setpoint filter 2 (general filter). 
Dependency: Refer to p1414, p1421 
 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 
0.000  10.000  0.700  -  Float  IM  T, U 
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 
0.00  50.00  0.00  ms  Float  IM  T, U 
Description: Sets the smoothing time constant (PT1) for the speed actual value. 
 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  -1000000.00  20000000.0
Description: Sets the fixed upper torque limit. 
 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. 
Description: Sets the fixed lower torque limit. 
 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. 
p1656 *  Activates current setpoint 
Description: Setting for activating/de-activating the current setpoint filter. 
Dependency: The individual current setpoint filters are parameterized as of p1658. 
If not all of the filters are required, then the filters should be used consecutively starting from filter 1. The 
drive unit displays the value in hex format. To know the logic (high/low) assignment to each bit, you must 
convert the hex number to the binary number, for example, FF (hex) = 11111111 (bin). 
p1658 *  Current setpoint filter 1 
denominator natural fre-
0.5  16000.0  1999.0  Hz  Float  IM  T, U 
 Sets the denominator natural frequency for current setpoint filter 1 (PT2, general filter). 
Dependency: The current setpoint filter 1 is activated via p1656.0 and parameterized via p1658 ... p1659.
