r1548[0...1] CO: Stall current limit torque-generating maximum / Isq_max stall
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2002 Dynamic index: -
Unit group: 6_2 Unit selection: p0505 Function diagram: -

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
p1552[0...n] CI: Torque limit upper scaling without offset / M_max up w/o offs
Access level: 3 Calculated: - Data type: Unsigned32 /
FloatingPoint32
Can be changed: T Scaling: PERCENT Dynamic index: CDS, p0170
Unit group: - Unit selection: - Function diagram: 6060

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.
p1553[0...n] Stall limit scaling / Stall limit scal
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180

Factory setting:
100.0 [%]
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.
