correction
(1) The characteristics of the mo-
tor are different.
(2) The magnetic pole position
detection method is not appropri-
ate.
(3) The value of 1st Starting
frequency 1 Holding time
(3004-19 hex) is insufficient.

Correction
Confirm that the settings of 1st
Base Frequency (3004-05 hex),
1st rated voltage at base
frequency (3004-06 hex), and
motor parameters (3007-02 to 04
hex, 3007-3D to 41 hex) are con-
sistent with the motor constants.
→ Perform auto-tuning.
Confirm that the magnetic pole
position detection method is suit-
able for the motor type.
→ Set 1st PM motor drive
magnetic pole position
detection mode (3007-1F hex)
according to the motor type.
Check if 1st Starting frequency
1 Holding time (3004-19 hex) is
set optimally when 1st PM
motor drive magnetic pole
position detection mode
(3007-1F hex) is set to 0 or 3.
→ Set a time that allows for at
least one rotation of the motor.
F24* ≥ P01* / 2 / F23* (P01*:
Number of poles, F23*: Starting

Prevention
Set the motor constant parame-
ters according to the motor char-
acteristics and perform auto-tun-
ing.
Set 1st PM motor drive
magnetic pole position
detection mode (3007-1F hex)
appropriately.
Set 1st Starting frequency 1
Holding time (3004-19 hex) to
an appropriate value.
