Description
V/f CL-V/f OLV CLV AOLV
Sets the internal speed feedback detection reduction unit gain as a magnification value.
Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
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.
V/f CL-V/f OLV CLV AOLV
Sets the d-axis current that flows to the motor during run at constant speed as a
percentage where E5-03 [PM Motor Rated Current (FLA)] = 100%.
V/f CL-V/f OLV CLV AOLV
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.
V/f CL-V/f OLV CLV AOLV
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)]
V/f CL-V/f OLV CLV AOLV
Sets the time constant that the drive uses when adjusting for voltage errors.
V/f CL-V/f OLV CLV AOLV
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
V/f CL-V/f OLV CLV AOLV
Sets the function that detects motor speed with high frequency injection.
Note:
When you set n8-57 = 1, do High Frequency Injection Auto-Tuning.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the output voltage limit to prevent saturation of the output voltage. Usually it is not
necessary to change this parameter.
Note:
• When A1-02 = 7, 8 [Control Method Selection = CLV/PM EZOLV], this
parameter is available in Expert mode.
• 200 V Class: 230.0 V
• 400 V Class: 460.0 V
V/f CL-V/f OLV CLV AOLV
Sets the gain of internal speed feedback detection suppression while the overvoltage
suppression function is operating as a magnification value. Usually it is not necessary to
change this parameter.
V/f CL-V/f OLV CLV AOLV
Usually it is not necessary to change this setting. Sets the Proportional gain that the
drive uses for speed estimation.
V/f CL-V/f OLV CLV AOLV
Selects the speed estimation method. Usually it is not necessary to change this setting.
0 : Method 1
1 : Method 2
V/f CL-V/f OLV CLV AOLV
Set n8-48 [Pull-in/Light Load Id Current] to the percentage of load current (q-axis
current) that you will apply, where E5-03 [PM Motor Rated Current (FLA)] = a setting
value of 100%.
V/f CL-V/f OLV CLV AOLV
Set n8-78 [Medium Load Id Current] to the percentage of load current (q-axis current)
that you will apply, where E5-03 [PM Motor Rated Current (FLA)] = a setting value of
100%.
V/f CL-V/f OLV CLV AOLV
Set n8-49 [Heavy Load Id Current] to the percentage of load current (q-axis current)
that you will apply, where E5-03 [PM Motor Rated Current (FLA)] = a setting value of
100%.
V/f CL-V/f OLV CLV AOLV
Sets the level of the pull-in current for mid-range loads.
