Parameter Specifications
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
Min: -1000000.00
Data type: Float
Description: Sets the fixed upper torque limit.
Danger: Negative values when setting the upper torque limit (p1520 < 0) can result in the motor accel-
erating in an uncontrollable fashion.
Notice: The maximum value depends on the maximum torque of the connected motor.
p1521 * Torque limit lower
Min: -20000000.00
Data type: Float
Description: Sets the fixed lower torque limit.
Danger: Positive values when setting the lower torque limit (p1521 > 0) can result in the motor acceler-
ating in an uncontrollable fashion.
Notice: The maximum value depends on the maximum torque of the connected motor.
p1656 * Activates current setpoint filter
Min: 0000 hex
Data type: U16
Description: Setting for activating/de-activating the current setpoint filter.
Bit 0: Activate filter 1

Bit 1: Activate filter 2

Dependency: The individual current setpoint filters are parameterized as of p1658.
Note: 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 frequency
Min: 0.5
Data type: Float
Description: 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.
