Description
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 load current level to start high efficiency control as a percentage of E5-03 [PM
Motor Rated Current (FLA)]. 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 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
Usually it is not necessary to change this setting. Sets the high efficiency control method
for IPM motor.
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, 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.
• When A1-02 = 8 [Control Method Selection = EZOLV], the default settings are:
• 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
Usually it is not necessary to change this setting. Sets the Proportional gain that the drive
uses for speed estimation.
