5-4-4-3 Adjustment Steps
※ You need to complete B-0 SM Autotune first (refer to Section 5-3-3).
1. Choose the motor control method.
Set Pr. C0-02 = 1: SVC.
2. Select the SM rotor initial detection method.
(1) If the mechanism or process allows reversal, set Pr. A3-17 = 1: Force alignment.
If the alignment force at start is insufficient, increase setting for Pr. A3-18 Force
Alignment Current Value; if the alignment current is too large, decrease setting for Pr.
A3-18 Force Alignment Current Value.
(2) If the motor is SPM and the system does not allow reversal, set Pr. A3-17 = 2: Pulse
inject.
If the operation direction at start is incorrect, increase setting for Pr. A3-20 Pulse Inject
Current Threshold; if the start current is too large or causes ocA, decrease setting for Pr.
A3-20 Pulse Inject Current Threshold.
(3) If the motor is IPM, PMA and SynRM and the system does not allow reversal, set Pr. A3-
17 = 3: HFI.
If the operation direction at start is incorrect, increase setting for Pr. A3-22 HFI
Amplitude; if there is evidence of electromagnetic noise, decrease setting for Pr. A3-22
HFI Amplitude.
3. Setup stop method.

4. Set the acceleration and deceleration time

C2-01
Decel Time 1
5. Execute no-load operation.
If the no-load current is too large, increase setting for Pr. E4-05 SM Torque COMP Gain.
6. Check if the motor rated frequency operates stably.
(1) If the motor resonates, increase setting for Pr. E4-03 SM FREQ Hunting Gain.
(2) If there is high-frequency motor excitation noise, decrease setting for Pr. A5-00 Carrier
Frequency Setting.
If there is low-frequency motor excitation noise, increase setting for Pr. A5-00 Carrier
Frequency Setting.
7. Execute load operation.
(1) If the motor vibrates in low-frequency or has insufficient loading capacity, increase
setting for Pr. E4-05 SM Torque COMP Gain to enhance the loading capacity for full
frequency range; however, it may cause over current if you set this parameter too large.
(2) If the output current is too large, decrease setting for Pr. E4-05 SM Torque COMP Gain
