This setting is used as a reference
value for protection functions.

To set V/f characteristics in a straight
line, set the same values for E1-07
and E1-09. In this case, the setting for
E1-08 will be disregarded.
Always ensure that the four frequen-
cies are set in the following order:
E1-04 (FMAX)
≥
E1-06 (FA) > E1-07

A2 signal level
selection
Selects the signal level input at multi-
function analog input A2.
0:0 to +10V (11 bit).
2:4 to 20 mA (9-bit input).
3:0 to 20 mA (9-bit input)
Ensure to switch S1-2 to “V” before
using a voltage input.
H3-09
Analog input
A2 function
selection.
Selects the multi-function analog
input function for terminal A2.
H3-13
Terminal A1/
A2 switching
Selects on which terminal the main
frequency reference can be input.
0:Use analog input 1 on terminal A1
for main frequency reference.
1:Use analog input 2 on terminal
A2 for main frequency reference.

Motor Protection
L1-01
Motor protec-
tion selection
0:Disabled
1:General-purpose motor protection
(fan cooled motor)
2:Inverter motor protection (externally
cooled motor)
3:Vector motor protection
When the Inverter power supply is
turned off, the thermal value is
reset, so even if it is enabled, pro-
tection may not be effective.
Power Loss Ride Through
L2-01
Momentary
power loss
detection
0:Disabled (DC bus undervoltage
(UV1) detection)
1:Enabled (Restarted when the
power returns within the time set
in L2-02. When L2-02 is
exceeded, DC bus undervoltage
is detected.)
2:Enabled while CPU is operating.
(Restarts when power returns dur-
ing control operations. Does not
detect DC bus undervoltage.)
Stall Prevention
L3-01
Stall preven-
tion selection
during accel
0:Disabled (Acceleration as set. With
a heavy load, the motor may stall.)
1:Enabled (Acceleration stopped
when L3-02 level is exceeded.
Acceleration starts again when
the current has fallen below the
stall prevention level).
2:Intelligent acceleration mode (Using
the L3-02 level as a basis, accelera-
tion is automatically adjusted. Set
acceleration time is disregarded.)
L3-02
Stall preven-
tion level dur-
ing accel
Effective when L3-01 is set to 1 or 2.
Set as a percentage of Inverter rated
current.
L3-04
Stall preven-
tion selection
during decel
0:Disabled (Deceleration as set. If
deceleration time is too short, a DC
bus overvoltage may result.)
1:Enabled (Deceleration is stopped
when the DC bus voltage
exceeds the stall prevention
level. Deceleration restarts when
the voltage falls below the stall
prevention level again.)
2:Intelligent deceleration mode
(Deceleration rate is automatically
adjusted so that the Inverter can
decelerate in the shortest possible
time. The set deceleration time is
disregarded.)
When a braking option (Braking Unit)
is used, always set to 0.
L3-05
Stall preven-
tion selection
during running
0:Disabled (Runs as set. With a
heavy load, the motor may stall.)
1:Deceleration using deceleration
time 1 (C1-02.)
2:Deceleration using deceleration
time 2 (C1-04.)
L3-06
Stall preven-
tion level dur-
ing running
Effective when L3-05 is 1 or 2.
Set as a percentage of the Inverter
rated current.
