5.9 n: Special Adjustments
■
n8-37: High Frequency Injection Amplitude
Sets the amplitude for High Frequency Injection as a percentage of the voltage (200 V or 400 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).
No.
n8-82
■
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.
n8-86
0: Disabled
After the rotor pole position is searched once, the drive starts using the detected rotor position. If the detected position
was wrong, an error will occur when the drive attempts running the motor. The initial pole search takes approximately 1.5
s.
1: Enabled
The rotor pole position is searched multiple times. Only if there is no difference between the search results, the drive
starts using the detected rotor position. Otherwise a dv8 error will be output. The initial pole search takes approximately
1.5 to 5.0 s.

Other Settings
Parameters n8-29 to n8-33 can be used to adjust the current control loop. These setting do normally not need to be
changed.
Parameter n8-62 sets a voltage limit in order to prevent voltage saturation.
■
n8-29: q-Axis Current Control Gain during Normal Operation
Sets the q-Axis proportional gain for the automatic current regulator.
No.
