Motor
Overheat
1
Motor Overheating Alarm
The
Inverter will stop or will continue
to
operate according to the setting of
L1-03.
The
motor has overheated.
Check
the size of the load and the
length
of the acceleration, deceler-
ation,
and cycle times.
Check
the V/f characteristics.
Check
the motor temperature
input
on terminals A1 and A2.
Motor
Overheat
2
Motor Overheating Fault
The
Inverter will stop according to the
setting
of L1-04.
The
motor has overheated.
Check
the size of the load and the
length
of the acceleration, deceler-
ation,
and cycle times.
Check
the V/f characteristics.
Check
the motor temperature
input
on terminals A1 and A2.
DynBrk
Resistor
Installed Braking Resistor Over-
heating
The
braking resistor is overheated and
the
protection function has operated if
it
has been enabled in L8-01.
The
deceleration time is too short and
the
regenerative energy from the
motor
is too large.
• Reduce
the load, increase the
deceleration
time, or reduce the
motor
speed.
• Change
to a Braking Resistor
Unit.
DynBrk
Transistr
Internal Braking Transistor Fault
The
braking transistor is not operating
properly.
-
• Try
turning the power supply
off
and on.
• Replace
the Inverter if the fault
continues
to occur.
Motor
Overloaded
Motor Overload
The
motor overload protection func-
tion
has operated based on the internal
electronic
thermal value.
The
load is too heavy. The accelera-
tion
time, deceleration time, and cycle
time
are too short.
Check
the size of the load and the
length
of the acceleration, deceler-
ation,
and cycle times.
The
V/f characteristics voltage is too
high
or too low.
Check
the V/f characteristics.
The
Motor Rated Current (E2-01) is
incorrect.
Check
the Motor Rated Current
(E2-01).
Inv
Over-
loaded
Inverter Overload
The
Inverter overload protection func-
tion
has operated based on the internal
electronic
thermal value.
The
load is too heavy. The accelera-
tion
time, deceleration time and cycle
time
are too short.
Check
the size of the load and the
length
of the acceleration, deceler-
ation,
and cycle times.
The
V/f characteristics voltage is too
high
or too low.
Check
the V/f characteristics.
The
Inverter capacity is too low.
Replace
the Inverter with one that
has
a larger capacity.
Over-

Overtorque Detected 1
There
has been a current greater than
the
setting in L6-02 for longer than the
setting
in L6-03.
-
• Make
sure that the settings in
L6-02
and L6-03 are appropri-
ate.
• Check
the mechanical system
and
correct the cause of the
overtorque.
Over-

Overtorque Detected 2
There
has been a current greater than
the
setting in L6-05 for longer than the
setting
in L6-06.
-
• Make
sure that the current set-
ting
in L6-05 and time setting in
L6-06
are appropriate.
• Check
the mechanical system
and
correct the cause of the
overtorque.
