2.2 List of parameters
Description: Display and connector output for the actual effective upper torque limit.
Note: The effective upper torque limit is reduced with respect to the selected upper torque limit p1520, if the current limit
p0640 is reduced or the rated magnetizing current of the induction motor p0320 is increased.
This may be the case for rotating measurements (see p1960).
The torque limit p1520 can be re-calculated using p0340 = 1, 3 or 5.
Description: Display and connector output for the actual effective lower torque limit.
Note: The effective lower torque limit is reduced with respect to the selected lower torque limit p1521, if the current limit
p0640 is reduced or the rated magnetizing current of the induction motor p0320 is increased.
This may be the case for rotating measurements (see p1960).
The torque limit p1520 can be re-calculated using p0340 = 1, 3 or 5.
Description: Displays the limit for the torque-generating current component using the stall calculation, the current limit of the
power unit as well as the parameterization in p0640.
Index: [0] = Upper limit
[1] = Lower limit
Description: Sets the scaling of the stall limit for the start of field weakening.
Danger: If the stall current limit is increased, then the q current setpoint can exceed the stall limit; as a consequence, a
hysteresis effect can occur when loading and unloading.
