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 [Motor Rated Current (FLA)]
• A1-02 = 8 [EZOLV]: E9-06 [Motor Rated Current (FLA)]
V/f CL-V/f OLV CLV AOLV
Sets the proportional gain of the current regulator. Usually it is not necessary to change this
setting.
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 high efficiency control method for IPM motor. Usually it is not necessary to
change this setting.
0 : Disabled
1 : Enabled (Vd)
2 : Enabled (Vd & Vq)
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, doHigh 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.
• When A1-02 = 8, the default setting is
–200 V Class: 230.0 V
–400 V Class: 460.0 V
V/f CL-V/f OLV CLV AOLV
Sets the proportional gain for output voltage control. Usually it is not necessary to change
this setting.
V/f CL-V/f OLV CLV AOLV
Sets the integral time for output voltage control. Usually it is not necessary to change this
setting.
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
Sets the filter time constant for output voltage control. Usually it is not necessary to change
this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain that the drive uses for speed estimation. Usually it is not necessary to change
this setting.
V/f CL-V/f OLV CLV AOLV
Sets the speed estimator integral time constant. It is available when n8-72 = 1 [Speed
Estimation Method Select = Method 2]. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Set the speed estimator differential gain. It is available when n8-72 = 1 [Speed Estimation
Method Select = Method 2]. Usually it is not necessary to change this setting.
