Setting 2: Pulse injection
A pulse signal is injected into the motor in order to detect the rotor position.
■
n8-36: High Frequency Injection Level
Sets the frequency level used for High Frequency Injection.
■
n8-37: High Frequency Injection Amplitude
Sets the amplitude for High Frequency Injection as a percentage of the voltage (200 V or 400 V).
■
n8-81: High Frequency Injection during Rescue Operation
Sets the frequency used for High Frequency Injection during Rescue Operation.
■
n8-82: High Frequency Injection Amplitude during Rescue Operation
Sets the amplitude for High Frequency Injection during Rescue Operation as a percentage of the voltage (200 V or 400
V).
■
n8-84: Polarity Detection Current
Sets the current level (E5-03) as a percentage for detecting polarity during Initial Polarity Estimation.
■
n8-86: Magnet Pole Search Error Detection Selection
Enables fault detection for Initial Polarity Estimation (dv8).
Setting 0: Disabled
After searching for the rotor pole position one time, the drive starts using the detected rotor position. If the detected
position is wrong, an error occurs when the drive attempts to run the motor. The initial pole search takes approximately
1.5 s.
Setting 1: Enabled
The rotor pole position search is executed multiple times. The drive starts using the detected rotor position only if there is
no difference between the search results. Otherwise a dv8 error will be output. The initial pole search takes approximately
1.5 to 5.0 s.
