Description
V/f CL-V/f OLV CLV AOLV
Sets the Initial Rotor Position Estimated Current as a percentage where E5-03 [PM
Motor Rated Current (FLA)] = 100%. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the current at the time of polar attraction as a percentage where E5-03 [PM Motor
Rated Current (FLA)] = 100%. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the length of the Current Starting Time, which is used for Z Pulse Offset Tuning.
Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the length of the Polar Attraction Time, which is used for Z Pulse Offset Tuning.
Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets how the drive detects the position of the rotor at start.
Note:
• When you operate an SPM motor, set n8-35 = 0. When you operate an IPM motor,
you can set n8-35 = 0 to 2.
• When you set n8-35 = 1, doHigh Frequency Injection Auto-Tuning.
0 : Pull-in
1 : High Frequency Injection
2 : Pulse Injection
V/f CL-V/f OLV CLV AOLV
Sets the injection frequency for high frequency injection.
Note:
• Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-
57 = 1 [HFI Overlap Selection = Enabled] to enable this parameter.
• The drive automatically calculates this value when High Frequency Injection
Auto-Tuning completes successfully.
V/f CL-V/f OLV CLV AOLV
Sets the high frequency injection amplitude as a percentage where 200 V = 100% for
200 V class drives and 400 V = 100% for a 400 V class drives. Usually it is not
necessary to change this setting.
Note:
• Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-
57 = 1 [HFI Overlap Selection = Enabled] to enable this parameter.
• The drive automatically calculates this value when High Frequency Injection
Auto-Tuning completes successfully.
V/f CL-V/f OLV CLV AOLV
Sets the low-pass filter shut-off frequency for high frequency injection.
Note:
• Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-
57 = 1 [HFI Overlap Selection = Enabled] to enable this parameter.
• The drive automatically calculates this value when High Frequency Injection
Auto-Tuning completes successfully.
V/f CL-V/f OLV CLV AOLV
Sets the response gain for the high frequency injection speed estimation.
Note:
• Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-
57 = 1 [HFI Overlap Selection = Enabled] to enable this parameter.
• When A1-02= 6 [Control Method Selection = AOLV/PM] and you do High
Frequency Injection Auto-Tuning, the drive automatically sets this parameter .
V/f CL-V/f OLV CLV AOLV
Sets the integral time constant for the high frequency injection speed estimation.
Usually it is not necessary to change this setting.
