Description
V/f CL-V/f OLV CLV AOLV
Sets the gain of the AFR function 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 that sets the rate of change for the AFR
function. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the time constant that sets the speed difference of the AFR
function. Use this parameter for speed searches or regeneration.
Usually it is not necessary to change this setting.
Description
V/f CL-V/f OLV CLV AOLV
Sets how much the drive lowers the output frequency during high-
slip braking as a percentage where E1-04 [Maximum Output
Frequency] = 100%.
V/f CL-V/f OLV CLV AOLV
Sets the maximum current output during high-slip braking as a
percentage where E2-01 [Motor Rated Current (FLA)] = 100%.
Also set the current suppression to prevent exceeding drive overload
tolerance.
V/f CL-V/f OLV CLV AOLV
Sets the dwell time, a length of time when high-slip braking is
ending and during which the motor speed decreases and runs at a
stable speed. For a set length of time, the drive will hold the actual
output frequency at the minimum output frequency set in E1-09.
V/f CL-V/f OLV CLV AOLV
Sets the time used to detect oL7 [High Slip Braking Overload],
which occurs when the output frequency does not change during
high-slip braking. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain value that the drive multiplies by the V/f pattern output
value during overexcitation deceleration to calculate the
overexcitation level.
V/f CL-V/f OLV CLV AOLV
Sets the function that injects harmonic signals during overexcitation
deceleration.

V/f CL-V/f OLV CLV AOLV
overexcitation deceleration, where the drive rated current = 100%
value.
V/f CL-V/f OLV CLV AOLV
overexcitation.
0 : Disabled
1 : Enabled Only when Rotating FWD
