Chapter 12 Description of Parameter SettingsCP2000

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”.
