5. Enter the correct values for Pr.00-10–Pr.00-15. Refer to motor capacity to set the
acceleration/deceleration time.
6. After auto-tuning is finished, check that Pr.00-31 Rs (ohm/phase), Pr.00-33 Ld (mH/phase),
Pr.00-34 Lq (mH/phase) and Pr.00-35 Back-EMF (Vrms/L-L @rated speed) all have values.
 Pr.00-30=10: IPM / SPM static test:
1. Note that it is suggested the brake should be locked.
2. Make sure that all the drive parameters are set to defaults and the motor wiring is correct.
3. Enter the correct values for Pr.00-10–Pr.00-15. Refer to motor capacity to set the
acceleration/deceleration time.
4. After auto-tuning is finished, check that Pr.00-31 Rs (ohm/phase), Pr.00-33 Ld (mH/phase),
Pr.00-34 Lq (mH/phase) and Pr.00-35 Back-EMF (Vrms/L-L @rated speed) all have values.
 Pr.00-30=6: Auto-measures the angle between the magnetic pole and the PG origin. Pay
attention to the following notes when measuring: (dynamic test)
1. Unload before auto-tuning.
2. If the drive controls the brake, the drive can auto-tune according to the normal sequence
after you complete the wiring and set the brake control parameters.
3. If the host controller controls the brake, make sure that the brake is in release status before
auto-tuning.
 Pr.00-30=8: Auto-measures the angle between the magnetic pole and the PG origin. Pay
attention to the following notes when measuring: (static test)
1. The motor can be loaded or unloaded before auto-tuning.
2. See the reference table for auto-tuning for Pr.00-20 (PG Signal Type). When Pr.00-20=3, set
Pr.03-90 bit9=1.
3. If the drive controls the brake, the drive can auto-tune according to the normal sequence
after you complete the wiring and set the brake control parameters.
4. If the host controller controls the brake, make sure that the brake is in release status before
auto-tuning.
5. Make sure the setting for Pr.00-23 is correct. Incorrectly setting Pr.00-23 causes incorrect
positioning of the magnetic pole and results in the wrong angle between the magnetic pole
and PG origin.
NOTE:
 In vector control mode, do not run motors in parallel.
 Do not use vector control mode if the motor rated power exceeds the rated power for the AC
motor drive.
 The no-load current is usually 20–50% of the rated current.
 The rated speed cannot be larger or equal to 120 f/p (f: output frequency Pr.00-13, p:
Number of Motor Poles Pr.00-15).
 After auto-tuning is finished, start the drive again to make it operate when the auto-tuning
command source is the external terminal.
 Note that if the contactor and brake are not controlled by the AC motor drive, release it
manually.
 Set Pr.00-30=6 (unloaded motor) for accurate calculation. If you need to execute this function
