This is used to calculate the armature IR voltage drop that is used as a correction to the measured armature voltage, to allow the back emf to be
computed.
This is the proportional voltage loop gain used during field weakening. If this parameter is set too high then instability during field weakening can
occur. When this is set too low the armature voltage may overshoot when base speed is reached. An increase in this gain increases the rate at which
the field weakens.
This is the integral voltage loop gain used during field weakening. If this parameter is set too high then instability during field weakening can occur.
When this is set too low the armature voltage may overshoot when base speed is reached. An increase in this gain increases the rate at which the
field weakens.
When this parameter is 0 the field weakening voltage loop does not run and the estimated speed is based on the field flux being 100 %. When this
parameter is 1 the field weakening voltage is enabled which allows the field to be weakened.
Permits the field current to be configured to the field economy level (Pr 5.67) automatically after the drive has been disabled for a period of time
(Pr 5.66). This is used to prevent the motor windings from overheating if the drive is stopped and the motor ventilation is switched off. This can also
be used to prevent condensation in the motor when it is not in use.
