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 [Max 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
[Mot 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.
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.
1 : Enabled@Both directions
2 : Enabled@FW direction
3 : Enabled@REV direction
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 for n4-60 [LoSpeed Comp Gain], n4-62 [Reg
LoSpd Cmp 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 [SpEstim Gain SwFrequency].
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 [SpEstim Gain SwFrequency].
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 [SpEstim Gain SwFrequency]. 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 [SpEstim Gain SwFrequency]. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the switching frequency for estimation gain for these parameters:
n4-63 [HF SpdEstim Response]
n4-64 [LF SpdEstim Response]
n4-65 [HF FlxEstim Response]
n4-66 [LF FlxEstim Response]
Usually it is not necessary to change this setting.
