Description
V/f CL-V/f OLV CLV AOLV
Sets the oscillation suppression gain of the speed estimation for high
frequency injection. Normally there is no need 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. Normally there is no need to change this
setting.
V/f CL-V/f OLV CLV AOLV
Sets the time constant used to match the pull-in current reference
value with the actual current value. Normally there is no need to
change this setting.
V/f CL-V/f OLV CLV AOLV
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.
V/f CL-V/f OLV CLV AOLV
Sets, in terms of a percentage, the d-axis current to be supplied to
the motor to run it at a uniform speed with a heavy load. Considers
E5-03 [Motor Rated Current] to be 100%. Normally there is no
need to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets, as a percentage, the pull-in current allowed to flow during
acceleration/deceleration, taking the motor rated current as a value
of 100%.
V/f CL-V/f OLV CLV AOLV
Sets the time constant used when compensating for voltage errors.
V/f CL-V/f OLV CLV AOLV
This parameter 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
Selects whether to perform a high frequency injection to detect
motor speed.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
To prevent saturation of the output voltage, set the output voltage
limit. Normally there is no need to configure this setting.
V/f CL-V/f OLV CLV AOLV
the overvoltage suppression function is working, as a magnification
value. Normally there is no need to configure this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain used for speed estimation. Normally there is no need to
change this setting.
V/f CL-V/f OLV CLV AOLV
Selects the speed estimation method. Normally there is no need to
change this setting.
0 : Conventional method
1 : A1000 method
V/f CL-V/f OLV CLV AOLV
Set n8-48 [Pull-In Current (for PM Motors)] to the level of the load
current (q-axis current) to be applied.
