n8-02: Pole Attraction Current
■
Sets the pull-in current used to detect rotor position. This setting rarely needs to be changed.
No.
n8-02
n8-35: Initial Rotor Position Detection Selection
■
Selects how the rotor position is detected at start.
No.
n8-35
Setting 1: High Frequency Injection
High frequency is injected in order to detect the rotor position. Some noise may be generated from the motor at start.
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.
No.
n8-36
■ n8-37: High Frequency Injection Amplitude
Sets the amplitude for High Frequency Injection as a percentage of the voltage (200 V or 400 V or 575 V).
No.
n8-37
■ n8-81: High Frequency Injection during Rescue Operation
Sets the frequency used for High Frequency Injection during Rescue Operation.
No.
n8-81
■ 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
or 575 V).
No.
n8-82 High Frequency Injection Amplitude during Rescue Operation
n8-84: Polarity Detection Current
■
Sets the current level (E5-03) as a percentage for detecting polarity during Initial Polarity Estimation.
No.
n8-84
n8-86: Magnet Pole Search Error Detection Selection
■
Enables fault detection for Initial Polarity Estimation (dv8).
No.
