Sets the terminal RP input signal frequency
that is equal to 100% of the value selected
in H6-01.
Sets the level of the value selected in H6-01
when a frequency with the value set in
H6-02 is input.
Sets the level of the value selected in H6-01
when 0 Hz is input.
Sets the pulse train input filter time
constant.
Sets the minimum frequency for the pulse
train input to be detected. Enabled when
H6-01 = 0, 1, or 2.

1: General purpose motor (standard fan
cooled)
2: Drive dedicated motor with a speed range
of 1:10
3: Vector motor with a speed range of 1:100
6: General purpose motor (50 Hz)
The drive may not be able to provide
protection when using multiple motors,
even if overload is enabled in L1-01. Set
L1-01 to 0 and install separate thermal
relays to each motor.
Sets the motor thermal overload protection
(oL1) time.
0: Disabled. Drive trips on Uv1 fault when
power is lost.
1: Recover within the time set in L2-02. Uv1
will be detected if power loss is longer than
L2-02.
2: Recover as long as CPU has power.
Uv1 is not detected.
3: KEB deceleration for the time set to
L2-02.
4: KEB deceleration as long as CPU has
power.
5: KEB deceleration to stop.
Sets the Power Loss Ride-Thru time.
Enabled only when
L2-01 = 1 or 3.

Description
Sets the minimum wait time for residual
motor voltage decay before the drive output
reenergizes after performing Power Loss
Ride-Thru.
Increasing the time set to L2-03 may help if
overcurrent or overvoltage occur during
Speed Search or during DC Injection
Braking.
Sets the time for the output voltage to return
to the preset V/f pattern during Speed
Search.
Sets the DC bus undervoltage trip level.
Sets the time required to decelerate from the
speed when KEB was activated to zero
speed.
Sets the time to accelerate to the frequency
reference when momentary power loss is
over. If set to 0.0, the active acceleration
time is used.
Sets the percentage of output frequency
reduction at the beginning of deceleration
when the KEB Ride-Thru function is
started.
Reduction = (slip frequency before KEB) ×
L2-08 × 2
Sets the time to perform KEB Ride-Thru.
Sets the desired value of the DC bus voltage
during KEB Ride-Thru.
0: Single Drive KEB Ride-Thru 1
1: Single Drive KEB Ride-Thru 2
2: System KEB Ride-Thru 1
3: System KEB Ride-Thru 2
0: Disabled.
1: General purpose. Acceleration is
paused as long as the current is above the
L3-02 setting.
2: Intelligent. Accelerate in the shortest
possible time without exceeding the L3-02
level.
Used when L3-01 = 1 or 2. 100% is equal
to the drive rated current.
Sets Stall Prevention lower limit during
acceleration when operating in the constant
power range. Set as a percentage of drive
rated current.
0: Disabled. Deceleration at the active
deceleration rate. An ov fault may occur.
1: General purpose. Deceleration is paused
when the DC bus voltage exceeds the Stall
Prevention level.
2: Intelligent. Decelerate as fast as possible
while avoiding ov faults.
3: Stall Prevention with braking resistor.
Stall Prevention during deceleration is
enabled in coordination with dynamic
braking.
4: Overexcitation Deceleration.
Decelerates while increasing the motor
flux.
5: Overexcitation Deceleration 2. Adjust
the deceleration rate according to the DC
bus voltage.
