Flux / if curve tuning (Flux / if curve)
The function of this curve is to model the real flux of the motor. The flux model allows the control of torque
current to better relate to torque. The figure below describes the relation between flux and flux current in condi

The field current (previous section) and the output voltage tunings (next section) must be carried
out when a Voltage control is required, whether the relevant flux curve has been defined or not.
The tunings scale is the following:

Figure 5.3.7.1: Curve convertion flux/current
Example:
A - With the default setting of the converter, there will be a linear characteristic (Curve A) of the flux current
(
Flux current
) when the parameter
Flux reference
changes.
Then:
Flux current max / Flux reference
= 100%
Flux current / Flux reference
= Motor nom flux
Flux current max / Flux reference
= 50%
Flux current / Flux reference
= 50% of Motor nom flux
B- Carrying out the tuning of the flux curve (see below tuning procedure ) the result will be emphasized by
curve B. The values of
Flux current
will follow a characteristic determined by the real flux percentage
