r1614 EMF maximum / EMF max
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2001 Dynamic index: -
Unit group: 5_1 Unit selection: p0505 Function diagram: 6725
Min:
- [Vrms]
Max:
- [Vrms]
Factory setting:
- [Vrms]
Description: Displays the actual maximum possible electromotive force (EMF) of the separately excited synchronous motor.
Dependency: The value is the basis for the flux setpoint.
The maximum possible EMF depends on the following factors:
- Actual DC link voltage (r0070).
- Maximum modulation depth (p1803).
- Field-generating and torque-generating current setpoint.
p1616[0...n] Current setpoint smoothing time / I_set T_smooth
Access level: 3 Calculated: CALC_MOD_REG Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6721, 6722
Min:
4 [ms]
Max:
10000 [ms]
Factory setting:
40 [ms]
Description: Sets the smoothing time for the current setpoint.
The current setpoint is generated from p1610 and p1611.
Note
This parameter is only effective in the range where current is injected for sensorless vector control.
r1623[0...1] Field-generating current setpoint (steady-state) / Id_set stationary
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2002 Dynamic index: -
Unit group: 6_2 Unit selection: p0505 Function diagram: 6723
Min:
- [Arms]
Max:
- [Arms]
Factory setting:
- [Arms]
Description: Displays the steady-state field generating current setpoint (Id_set).
Note
For index 1:
Reserved.
r1624 Field-generating current setpoint total / Id_setp total
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2002 Dynamic index: -
Unit group: 6_2 Unit selection: p0505 Function diagram: 6640, 6721,
6723, 6727
Min:
- [Arms]
Max:
- [Arms]
Factory setting:
- [Arms]
Description: Displays the limited field-generating current setpoint (Id_set).
This value comprises the steady-state field-generating current setpoint r1623 and a dynamic component that is only
set when changes are made to the flux setpoint.
