 Check if the motor can be separated from the pump
 If it can be separated, set the Pr.01-07 as 5 and carry out the parameter measurement of the
synchronous motor
 If it cannot be separated, open the safety valve, set Pr.01-07 as 5 and carry out the parameter
measurement of the synchronous motor
Motor Parameter Auto Tuning
Setting value
of Pr.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: Dynamic rolling test for synchronous permanent-magnet (SPM)
motor
13: Dynamic rolling test for interior permanent-magnet (IPM)
synchronous motor
 During the automatic measurement process of the synchronous 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.01-22 to 01-25. If the digital 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 Pr.01-27

 The machine will shut off power and then supply power again
 Test ru n
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.
