angle detection. Refer to the setting for Pr.01-01 before you adjust this parameter.
 If the setting value for Pr.00-17 is lower than Pr.10-51*10, then increase the frequency of the
carrier wave.
 Pr.10-51 is valid only when Pr.10-53 = 2.
 Injection Magnitude
Default:
15.0/ 30.0/ 30.0/ 30.0
Settings 0.0–200.0 V
230V Series: 0.0–100.0 V
460V Series: 0.0–200.0 V
575V Series: 0.0–200.0 V
690V Series: 0.0–200.0 V
 The parameter is the magnitude command for the high frequency injection signal in PM SVC
control mode.
 Increasing the parameter can increase the accuracy of the angle estimation, but the
electromagnetic noise might be louder if the setting value is too high.
 The system uses this parameter after the motor auto-tunes parameters. This parameter
influences the angle estimation accuracy.
 When the ratio of the salient pole (Lq/Ld) is lower, increase Pr.10-52 to make the angle
detection more accurate.
 Pr.10-52 is valid only when Pr.10-53 = 2.

PM Initial Rotor Position Detection Method
Default: 0
Settings 0: Disable
1: Internal 1/4 rated current attracting the rotor to zero degrees
2: High frequency injection
3: Pulse injection
 Set to 2 for IPM; set to 3 for SPM. If these settings cause problems, then set the parameter to
“1”.
