SETTING DEF SETTING/RANGE
Protection
Function
L1-01
Motor Overload
Protection
Selection
Sets the motor thermal overload
protection (oL1) based on the
cooling capacity of the motor.
NOTICE: When multiple motors
are used the drive may not be able
to provide protection, even if it is
enabled in L1-01. Set L1-01 to
“0” and ensure each motor has a
thermal relay installed.
0

0: Disabled
1: Standard Fan Cooled
(speed range < 10:1)
2: Standard Blower Cooled
(speed range ≥ 10:1)
L1-02 Motor Overload
Protection Time
Sets the motor thermal overload
protection (oL1) time.
1.0
8.0
0.1 to 5.0 minutes
L1-13
Continuous
Electrothermal
Operation
Selection
Determines whether or not to hold
the electrothermal value when the
power supply is interrupted.

L2-01
Momentary Power
Loss Operation
Selection
Enables and disables the
momentary power loss function
2
0
0: Disabled – Drive trips on (Uv1)
fault when power is lost
1: Power Loss Ride-Thru Time –
Drive will restart if power returns
within the Power Loss Ride-Thru
Time
2: CPU Power Active – Drive will
restart if power returns as long as
the CPU is working
L3-01
Stall Prevention
Selection during
Acceleration
Selects the Stall Prevention
method used to prevent excessive
current during acceleration.
1
1
0: Disabled – Motor accelerates at
active acceleration rate. The
motor may stall if load is too
heavy or accel time is too short.
1: General Purpose – When output
current exceeds L3-02 level,
acceleration stops. Acceleration
will continue when the output
current level falls below L3-02
level.
L3-02
Stall Prevention
Level during
Acceleration
Used when L3-01 = 1. 100% is
equal to the drive rated current.
Decrease the set value if stalling
or excessive current occurs with
default setting.
150
150 0 to 150%
L3-04
Stall Prevention
Selection during
Deceleration
When using a braking resistor,
used setting “0”. Setting “3” is used
in specific applications.
1
1
0: Disabled – The drive decelerates
at the active deceleration rate.
If the load is too large or the
deceleration time is too short, an
ov fault may occur.
1: General Purpose – The
drive decelerates at the active
deceleration rate, but if the main
circuit DC bus voltage reaches
the Stall Prevention level,
deceleration will stop.
Deceleration will continue once
the DC bus level drops below the
Stall Prevention level.
4: Overexcitation Deceleration –
Decelerates with the flux
level determined by n3-13
(Overexcitation Gain).
