Description
V/f CL-V/f OLV CLV AOLV
Sets the speed estimation response for high frequency injection.
Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the oscillation suppression gain of the speed estimation for high
frequency injection. Usually it is not necessary to change this
setting.
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
parameter.
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 parameter.
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. This parameter is 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 pull-in current that can flow during acceleration/
deceleration as a percentage where E5-03 [PM Motor Rated Current
(FLA)] = 100%.
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.
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 setting.
V/f CL-V/f OLV CLV AOLV
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 gain that the drive uses for speed estimation. Usually it is
not necessary to change this setting.
