I-red-TE:
Current limit that becomes effective due to power module (IGBT) temperature. The
temperature in units in which the current limit becomes equal to I nom.
See I-red-TD. Setting I-
red-TE is zero disables the function. This is an optional parameter.
o
I-red-TM:
Ramp reduction from I red-TM to M-temp
– Number is motor temperature. The
reduction state changes as soon as the motor temperature is above the configured value. Can
only be used when the temperature sensor in the motor is linear.

8.5.4 Configuring magnetic field weakening parameters
Fill in the following fields:
•
Id nom:
Magnetizing current in percent of the nominal current of the motor (from “Motor data”
group). By optimizing this parameter (can only be done after additional motor parameters are
configured
) it is possible to achieve higher speed with the same
load, resulting in higher speed in maximum modulation while in operation
•
.
Id min:
min.
Id-current 50-80%
•
V red:
Output voltage for the field weakening (80%)
•
V kp:
Control amplification for the field weakening (500-2000)
•
V-Ti:
Rated time field control (0-2000). Too high value will cause oscillation
