2.2 List of parameters
r1548[0...1] CO: Stall current limit torque-generating maximum / Isq_max stall
Access level: 4
Can be changed: -
Unit group: 6_2
Min
- [Arms]
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
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
p1552[0...n] CI: Torque limit upper scaling without offset / M_max up w/o offs
Access level: 3
Can be changed: T
Unit group: -
Min
-
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.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
p1553[0...n] Stall limit scaling / Stall limit scal
Access level: 4
Can be changed: U, T
Unit group: -
Min
80.0 [%]
Description: Sets the scaling of the stall limit for the start of field weakening.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
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.
p1554[0...n] CI: Torque limit lower scaling without offset / M_max low w/o offs
Access level: 3
Can be changed: T
Unit group: -
Min
-
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.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
p1560[0...n] Moment of inertia estimator accelerating torque threshold value / J_est M thresh
Access level: 3
Can be changed: C(3), U, T
Unit group: -
Min
0.10 [%]
Description: Sets the threshold for the accelerating torque for the moment of inertia estimator.
