432 Parameters
Defines the relative output voltage boost at zero speed (IR
compensation). The function is useful in applications with a
high break-away torque where direct torque control (DTC
mode) cannot be applied.
IR compensation for scalar motor control

0.00 … 50.00%
Voltage boost at zero speed in percent of nominal motor
voltage.
1 = 1%
Motor model
temperature
adaptation
Selects whether the temperature-dependent parameters
(such as stator or rotor resistance) of the motor model adapt
to actual (measured or estimated) temperature or not.
See parameter group
for
selection of temperature measurement sources.
Disabled
Temperature adaptation of motor model disabled.

Activates hexagonal motor flux pattern in the field weakening
area, ie. above the limit defined by parameter
Hexagonal field weakening point

Note:
This parameter is only effective in scalar motor control
).
Off
The rotating flux vector follows a circular pattern.
0
On
The flux vector follows a circular pattern below, and a
hexagonal pattern above, the hexagonal field weakening point
