value. Normally there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
This parameter sets the time constant that determines the rate of
change for the AFR function. Normally there is no need to change
this setting.
V/f CL-V/f OLV CLV AOLV
This parameter sets the time constant that determines the variation
in speed of the AFR function. Use this parameter when performing
speed searches or regeneration. Normally there is no need to change
this setting.
Description
V/f CL-V/f OLV CLV AOLV
Sets the amount by which the output frequency is to be lowered
during high-slip braking, as a percentage of E1-04 [Maximum
Output Frequency], which represents the 100% value.
V/f CL-V/f OLV CLV AOLV
Sets the maximum current output during high-slip braking as a
percentage of E2-01 [Motor Rated Current (FLA)], which
represents the 100% value. Set the current suppression so that the
drive's overload tolerance is not exceeded.
V/f CL-V/f OLV CLV AOLV
This sets the dwell time, a period of time in which the motor has
slowed down and runs at a steady speed, which occurs when the
high-slip braking is nearing completion. For a predetermined
amount of time only, the actual output frequency will be held at the
minimum output frequency that was set for E1-09.
V/f CL-V/f OLV CLV AOLV
Sets the time used for detection of oL7 [Motor Overload Protection
During High Slip Braking], which is implemented at times when for
some reason the output frequency did not change during high-slip
braking. Normally there is no need to configure this setting.
V/f CL-V/f OLV CLV AOLV
The overexcitation level is determined by multiplying the gain set
by this parameter with the V/f pattern output value during
overexcitation deceleration.
V/f CL-V/f OLV CLV AOLV
Enables or disables the function that injects harmonic signals during
overexcitation deceleration.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
This sets, as a percentage value, the upper limit of the current
suppressed at the time of overexcitation deceleration, taking the
drive rated current as a value of 100%.
V/f CL-V/f OLV CLV AOLV
This parameter selects the direction of motor rotation of motors for
which overexcitation operation is applied.
0 : Enabled in both directions
1 : Enabled only when rotating FWD
2 : Enabled only when in REV
