During the automatic measurement process of the induction motor, the digital keypad will
show the message “tun”. After the measurement is finished, the motor automatically shuts
down, and the measurement values are stored into Pr.01-13 to Pr.01-16. If the digital keypad
shows “AUE”, please check if the wiring is correct and if the parameters are set correctly.
The machine will shut off the power and then supply the power again

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 no-load 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.
