Injection Magnitude
Default: 15.0 / 30.0
Settings 115V / 230V series: 100.0 V
460V series: 200.0 V
Note: The setting range varies depending on the voltage.
 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 when the motor’s parameter is “Auto”. 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.

Angle detection method
Default: 0
Settings 0: Disabled
1: Force 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.
