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, where E2-01
[Motor Rated Current (FLA)] is 100%. Also set the current suppression to prevent
exceeding drive overload tolerance.
Note:
The upper limit to the setting range changes when the setting for C6-01 [Normal /
Heavy Duty Selection] changes.
• 150% when C6-01 = 0 [Heavy Duty Rating]
• 110% when C6-01 = 1 [Normal Duty Rating]
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 parameter.
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 as a percentage of the drive rated current.
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
Description
V/f CL-V/f OLV CLV AOLV
Sets a compensation gain to improve the control qualities for motoring loads in the low
speed range.
V/f CL-V/f OLV CLV AOLV
Sets a frequency at which the settings n4-60 [Motoring Low Speed Comp Gain] and n4-
62 [Regen Low Speed Comp Gain] are enabled. When the output frequency < n4-61, the
drive adjusts the torque to agree with the settings for n4-60 and n4-62. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets a compensation gain to improve the control qualities for regenerative loads in the
low speed range.
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness of the speed estimation in high speed ranges, where the output
frequency is ≥ n4-67 [Estimate Gain Switchover Freq].
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness of the speed estimation in low speed ranges, where 0 ≤ the
output frequency, which is < n4-67 [Estimate Gain Switchover Freq].
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness of the magnetic flux estimation in high speed ranges, where the
output frequency is ≥ n4-67 [Estimate Gain Switchover Freq]. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness of the magnetic flux estimation in low speed ranges, where 0 ≤
the output frequency, which is < n4-67 [Estimate Gain Switchover Freq]. Usually it is
not necessary to change this setting.
