Parameter to set the flux setpoint as a % relative to the rated motor flux.
Index:
P1570[0] : 1st. Drive data set (DDS)
P1570[1] : 2nd. Drive data set (DDS)
P1570[2] : 3rd. Drive data set (DDS)
Note:
- In the base speed range, the flux setpoint P1570 is converted into the field-generating current
component isd (P1570 = 100% corresponds to r0331).
- For values below 100%, the drive is under-magnetized and above this, is over-magnetized.
- If P1570 is set to more than 100%, then the flux setpoint, depending on the load, is increased from
100% (under no-load conditions) to this value (under rated load, refer to the diagram).
- If in so doing, the maximum drive inverter output voltage is reached, the rotor flux is reduced in order to
keep the output voltage constant (or the EMF) with increasing speed.
- The maximum possible output voltage r0071 of the drive inverter is determined by the DC link voltage
r0026 and the maximum modulation depth P1803 in the gating unit.
