keypad shows “AUE”, please check if the wiring is correct and if the parameters are set
correctly.
 Set the value of Parameter 01-07 as 4 and press [Run]. When the operation is complete, the
PG offset angle of PM motor is written to Parameter 01-27
Motor Parameter Auto Tuning
Setting value
of Parameter
01-07
0: No function
1: Rolling test for induction motor(IM) (Rs, Rr, Lm, Lx, no-load current)
2: Static test for induction motor(IM)
3: Reserved
4: Auto measure the angle between magnetic pole and PG origin
5: Rolling test for PM motor
 The machine will shut off power and then supply power again
 Test run
When the motor is in a no-load state, the speed command is set to 10 rpm for low-speed test
run. Make sure that the output current value is close to the zero current.
If no error occurs, gradually increase the value of speed command to the highest speed.
Make sure that the pump’s oil supply direction is the forward direction of the motor.
Step 2. Estimation of Inertia
 Set the speed command as 1000 rpm
 Set the Parameters 01-05 & 01-06 = 0.3~0.5 seconds

2: Estimation of inertia
 Check if the value of Parameter 01-32 is converged. If it is converged, stop the operation. If
not, switch the rotation direction after the speed is stable.
