6.2.9 Group F08 Asynchronous Motor 1 Parameters
The idling exciting current (F08.11) can be calculated by the motor’s rated current (F08.02) and
motor’s power factor (F08.05) or detected by motor auto-tuning (F08.06 = 2).
The relationship between rated torque current, idling exciting current and motor’s rated current is
below:
Rated torque current = F08.05 × F08.02
Idling exciting current F08.11 =
