19.11 Ke factor in V/Nnom
Ke factor in V/N
nom
or the effective value of the phase-to-phase induced voltage at the
nominal speed. It results from the parameters
Z107.7– Nominal speed and Z107.20– Ke
factor (in V/1000 rpm) at a magnetic flux = 100%.
When the Ke factor Z107.20– in the enabled state is changed then the internally used
value in the controller is smoothed in order to reduce interferences in the controller. The
temporal change of the smoothing Ke factor can be monitored in the parameter 19.11.
19.12 Cutt-off frequency PT1-filter Isq set value
Cut-off frequency of the iq set value filter. The filter is switched off by setting this param-
eter to 0.
19.17 Isq additive set value
Additional set value for current.
19.21 Isq additive set value 2
Second additional set value for current.
