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.
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.
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.
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 .
Sets the integral time constant for the high frequency injection speed estimation. Usually it is not
necessary to change this setting.
Sets the internal speed feedback detection reduction unit gain as a magnification value. Usually it is
not necessary to change this setting.
Sets the gain to compensate for phase differences. Usually it is not necessary to change this setting.
Sets the time constant the drive uses to align the pull-in current reference value with the actual
current value. Usually it is not necessary to change this setting.
On the basis that parameter E5-03 [Motor Rated Current (FLA)] is the 100% value, this parameter
sets the d-axis current that flows to the motor during run at constant speed as a percentage.
Sets the d-axis current to that the drive will supply to the motor to run it at a constant speed with a
heavy load. Considers E5-03 [PM Motor Rated Current (FLA)] to be 100%. Usually it is not
necessary to change this setting.
Sets the load current level at which heavy load control starts where E5-03 [Motor Rated Current
(FLA)] is 100%. Usually it is not necessary to change this setting.
Sets the pull-in current allowed to flow during acceleration/deceleration as a percentage of the motor
rated current.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor rated current.
• A1-02 = 5 [OLV/PM]: E5-03 [PM Motor Rated Current (FLA)]
• A1-02 = 8 [EZOLV]: E9-06 [Motor Rated Current (FLA)]
Sets the time constant that the drive uses when adjusting for voltage errors.
Sets the ratio between motor inertia and machine inertia.
0 : Below 1:10
1 : Between 1:10 and 1:30
2 : Between 1:30 and 1:50
3 : Beyond 1:50
Sets the high efficiency control method for IPM motors. Usually it is not necessary to change this
setting.
0 : Disabled
1 : Enabled (Vd)
2 : Enabled (Vd & Vq)
