Description
V/f CL-V/f OLV CLV AOLV
Sets the gain for the hunting prevention function. This parameter functions
best with a high carrier frequency. Usually it is not necessary to change this
setting.
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness of the hunting prevention function. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the time for voltage detection circuit calibration during startup. Usually
it is not necessary to change this setting.
Description
V/f CL-V/f OLV CLV AOLV
Sets the gain of the AFR function for forward run 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 to determine the variation in speed of the AFR
function. Use this parameter during regeneration. Usually it is not necessary
to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain of the AFR function for reverse run as a magnification value.
Usually it is not necessary to change this setting.
Description
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.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the upper limit of the current that is suppressed at the time of
overexcitation deceleration, where the drive rated current = 100% value.
V/f CL-V/f OLV CLV AOLV
Sets the direction of motor rotation where the drive will enable
overexcitation.
0 : Disabled
1 : Enabled Only when Rotating FWD
2 : Enabled Only when Rotating REV
