Standstill current and stabilisation current (nn.01, nn.10)
The currents nn.01 "stabilisation current" and nn.10 "standstill current" can be switched off with bit 0 of nn.00.
The starting phase with activated currents runs more steady. In such a way this adjustment should not be
changed!
The values are limited to ½ of the HSR current In.18 if the rated motor current is higher than the inverter rated
current.
Stator resistance adaption
The stator resistance changing by temperature inuences can affect the behavior at low speed as well as the
start. The RS adaptation adjusts the stator resistance and stabilizes the motor model therefore.
The I-part of the adaptation can be adjusted with nn.06 "rs adaption factor". The rs adaptation becomes active
with ru.17 "active current" > nn.
01.
EMC adaption
The EMC changing by load and temperature inuences is adjusted at upper speed.
The adaption becomes active at actual speed ru.07 > ¼ of the rated speed dr.24 and improves the accuracy
of the actual torque display ru.12.
Observer
The observer amplies the inuence of the measured currents in the model. The most effects become notice-
able in the upper speed range.
The value must be increased if current oscillations occur at e.g. applications with high frequency.
The observer factor can be adjusted with nn.07 "observer factor".
