Description
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the drive operation after a momentary power loss.
0 : Disabled
1 : Enabled
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the drive operation after a momentary power loss..
0 : Timer Controlled
1 : While CPU Active
2 : KEB Mode
3 : KEB Stop Mode
4 : KEB Decel to Stop
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the maximum time that the drive will wait until trying to restart after power loss.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the minimum time to continue the drive output block (baseblock) after a baseblock.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the time for the drive output voltage to go back to correct voltage after completing
speed searches.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the voltage at which a Uv1 [DC Bus Undervoltage] fault is triggered or at which
the KEB function is activated. Usually it is not necessary to change this setting.
NOTICE: Damage to Equipment. When you set this parameter
to a value lower than the default, you must install an AC
reactor on the input side of the power supply. If you do not
install an AC reactor, it will cause damage to the drive circuitry.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the deceleration time during KEB operation used to decrease the maximum output
frequency to 0.
Note:
When L2-29 = 2, 3, or 4 [KEB Method = Single KEB2 Ride-Thru, System KEB1
Ride-Thru, or System KEB2 Ride-Thru] and you do KEB Auto-Tuning, the drive
will automatically set this value.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the acceleration time to return the frequency to the frequency reference before a
power loss after canceling KEB operation.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the quantity of output frequency reduction used when KEB operation starts as a
percentage of the motor rated slip before starting KEB operation.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the quantity of output frequency reduction used as a percentage of E2-02 [Mot
Rated Slip] when KEB operation starts.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the minimum length of time to operate the KEB after the drive detects a
momentary power loss.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the target value that controls the DC bus voltage to a constant level in Single Drive
KEB Ride-Thru 2. Sets the DC bus voltage level that completes the KEB operation for
all other KEB methods.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the KEB function operation mode.
1 : Single KEB1 Ride-Thru
