Description: Displays the torque limit to limit the speed controller output.
Index: [0] = Upper limit
[1] = Lower limit
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 signal source for the scaling of the upper torque limiting to limit the speed controller output without taking
into account the current and power limits.
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 hys-
teresis effect can occur when loading and unloading.
Description: Sets the signal source for the scaling of the lower torque limiting to limit the speed controller output without taking
into account the current and power limits.
