Parameter 14-32 Current Lim Ctrl, Filter Time
Table 493: Parameter 14-32 Current Lim Ctrl, Filter Time
14-32 Current Lim Ctrl, Filter Time
Default value: Size related
Conversion index: -4
Controls the current limit control low-pass filter. This makes it possible to react to peak values or to average values. When selecting
average values, it is sometimes possible to run with higher output current and instead trip on the hardware limit for current. Howev-
er, the control reacts slower as it does not react on immediate values.

Description
In this mode, the drive calculates the optimal torque output. Measured DC-link voltage determines
the phase-to-phase motor voltage. Magnetizing reference is based on the actual voltage and utilizes
the information about the model of the motor.
The drive reduces torque output. The drive sets the magnetizing reference inversely proportional to
the speed using a static curve that shows the relationship between DC-link voltage and the speed.
