SIEPCYEUOQ2V01A Q2V Technical Manual
Description
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the function to prevent hunting.
Note:
When you replace a V1000-series drive with a Q2V drive, set n1-01 = 1 [HuntPrev
Selection = Enabled].
0 : Disabled
1 : Enabled
2 : Enabled (High Carrier)
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the performance of the hunting prevention function. Usually it is not necessary to
change this parameter.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the primary delay time constant of the hunting prevention function. Usually it is
not necessary to change this parameter.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the performance of the hunting prevention function. This parameter adjusts
Reverse run. Usually it is not necessary to change this parameter.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the oscillation suppression function for the DC bus voltage.
0 : Disabled
1 : Enabled
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Adjusts the responsiveness of the oscillation suppression function for the DC bus
voltage. Set n1-13 = 1 [DCBus Stab.Control = Enabled] to enable this parameter.
Description
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the gain of the AFR function as a magnification value. Usually it is not necessary
to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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 OLV OLV/PM AOLV/PM EZOLV OLV/PM
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 OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the amount by which the output frequency is to be lowered during high-slip
braking, as a percentage of E1-04 [Max Output Frequency], which represents the 100%
value.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the maximum current output during high-slip braking as a percentage, where E2-01
[Mot 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 [ND/HD
Duty Selection] changes.
• 150% when C6-01 = 0 [HD Rating]
• 120% when C6-01 = 1 [ND Rating]
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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.
