99.05 Motor flux current
Range: 0.1 ~ 400.0 A in 0.1 A
Initial value: depend on VFD models
Program the no load (flux) current value
Not all motors will have this information on the nameplate
The value is approximately 30% of rate current
99.06 Motor rated slip
Range: 0.01 ~ 10.0 % in 0.1 %
Initial value: depend on VFD models
Program the slip percent of the motor rated nameplate rpm
Rated slip frequency: [(rated speed – speed of nameplate) / rated speed] x 100
Ex) [(1800rpm – 1750rpm) / 1800rpm] X 100 = 2.78%
99.07 Motor Pole setting
2: 2 Poles
4: 4 Poles ----- Initial value
6: 6 Poles
8: 8 Poles
Program a number of poles to the corresponding motor used with the VFD
Ex1) 2 Poles for 3600rpm (60Hz), 3000rpm (50Hz)
Ex2) 4 Poles for 1800rpm (60Hz), 1500rpm (50Hz)
Ex3) 6 Poles for 1200rpm (60Hz), 1000rpm (50Hz)
Ex4) 8 Poles for 900rpm (60Hz), 750rpm (50Hz)
99.08 Auto tuning
0: Disable ----- Initial value
1: Enable
Program to enable auto tuning function
Motor parameters are calculated using the internal auto tuning algorithm and
automatically set for sensorless vector control design
Auto tuning process
1. Put the data at
'99.01' (Motor capacity) ~ '99.07' (Motor Pole setting)
2. Set 1 at
'99.08' (Auto tuning)
3. Push the Run button on the keypad
