Delta HES Series Instructions For Use Manual page 77

4. Set Pr01-07 as 1 and then press the RUN button on the keypad. The auto tuning process
for the motor is carried out immediately. (Note: the motor starts running).
5. After the process is finished, check if the motor's parameters (Pr01-13 ~Pr01-16) have
been automatically entered with the measurement data.
6. Equivalent circuit of the motor
NOTE
* When the static tuning (Pr01-07 = 2) is used, you must enter the no-load current to the motor. It is generally 20 to
50% of the rated current.
 If the parameter is set as 5, it will perform the parameter automatic tuning for the synchronous
motor. In this case, press the [Run] button to perform the automatic measurement operation
immediately. After the measurement is complete, the values are filled into Parameters 01-22
(Rs), 01-23 & 24 (Ld & Lq), 01-25 (Back EMF of the synchronous motor), respectively.
Synchronous motor AUTO-Tuning procedure: (static measurement)
1. All parameters of the Hybrid Servo Controller are set to factory settings and the motor is
connected correctly.
2. Set the rated current 01-17, rated power 01-18, rated speed 01-19, and number of poles
01-20 of the motor with correct values, respectively. For the acceleration/deceleration
time, set the values according to the motor's capacity.
3. Set Parameter 01-07 as 5 and then press the RUN button. The auto tuning process for
the motor is carried out immediately. (Note: the motor starts running slightly).
4. After the process is finished, check if the motor's parameters (parameters 01-22 ~ 01-25)
have been automatically entered with the measurement data.
 If the Parameter is set as 4, the automatic measurement of the angle between magnetic pole
and the PG origin for the synchronous motor is performed. In this case, press the [Run] button
to immediately perform automatic measurement. The measured data will be entered into
Parameter 01 -27.
Auto-Tuning process for Synchronous Motor of the Angle between Magnetic Poles and PG
Origin:
1. Set Pr01-07 as 5 <Rolling test for PM motor> and run this setting. Or input the correct
vales to Pr01-03, Pr01-17 to Pr01-25.
2. Before tuning, it is recommended to separate the motor and the load.
3. Set Pr01-07 as 4 and then press the RUN button on the keypad. The auto tuning process
for the motor is carried out immediately. (Note: the motor starts running).
4. After the process is complete, check if the values for the angle between magnetic poles
and PG origin have been automatically entered in Pr01-27.
