Note:-
No-load motor voltage (02-19) & 17-08
Parameter determines the rated flux during motor’s rated rotation in SLV or SV control mode.
Set the value of this parameter to the same value as parameter 17-08.
A value of 10~50V below the rated input voltage level (parameter 17-03) ensures that the
motor is capable of providing adequate torque performance when operating at nominal speed
(or higher speed).
Setting the value too small can result in a reduction in no-load current, weakened motor flux
and an increase in motor current while the motor is loaded, causing a reduction in torque
performance.
For high KW rating (55KW and above) set this closer to the supply voltage.
Motor excitation current 17-09 & (02-09)
This parameter is automatically set during auto-tune. No adjustment required.
For static tuning & Resistance tuning this parameter needs to be adjusted
Set to 1/3 of the motor rated current parameter ( 17-02).
