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.
p1554[0...n] CI: Torque limit lower scaling without offset / M_max low 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

- Factory setting:
1
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.
r1566[0...n] Flux reduction torque factor transition value / Flux red M trans
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: PERCENT Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6790
Min:
- [%] Max:
- [%] Factory setting:
- [%]
Description: The following applies for a synchronous reluctance motor:
Displays the transition value for the start of the evaluation of the optimum flux characteristic.
The value is referred to the rated motor torque.
Note
The transition value corresponds with the lower limit of the flux setpoint (p1581).
For a lower absolute torque setpoint, the flux setpoint remains at the lower limit (p1581).
p1570[0...n] CO: Flux setpoint / Flex setp
Access level: 3 Calculated:
CALC_MOD_LIM_REF
Data type: FloatingPoint32
Can be changed: T, U Scaling: PERCENT Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6722
Min:
50.0 [%] Max:
200.0 [%] Factory setting:
100.0 [%]
Description: Sets the flux setpoint referred to rated motor flux.
The following applies for a synchronous reluctance motor:
Scaling the flux setpoint.
NOTICE
A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
