(1) The inverter's ambient tem-

range.
(2) The value of Torque Boost
Voltage (3004-0A hex, 3009-06
hex) is too high.
(3) The acceleration/deceleration
time is short.
(4) The load is large.

Correction
Measure the ambient tempera-
ture.
→ Lower the ambient tempera-
ture, for example, by improving
the ventilation in the panel.
Check the value of Torque
Boost Voltage (3004-0A hex,
3009-06 hex) to be sure that low-
ering the value does not cause a
stall.
→ Adjust the value of Torque
Boost Voltage (3004-0A hex,
3009-06 hex).
Recalculate the required acceler-
ation/deceleration torque and ac-
celeration/deceleration time
based on the load's moment of
inertia and acceleration/decelera-
tion time.
→ Increase the values of 1st
Acceleration Time 1 (3004-08
hex), 1st Deceleration Time 1
(3004-09 hex), 3005-0B hex to
3005-10 hex, and 3008-39 hex.
Measure the output current.
→ Reduce the load. (Use 1st
Overload Early Warning
Detection Level (3005-26 hex),
2nd Overload Warning
Detection Level (3005-38 hex),
and Overload early warning 2
Level (3005-23 hex) to reduce
the load before overloading oc-
curs. In winter, the load may be-
come larger.)
→ Reduce the value of Carrier
Frequency (3004-1B hex).
→ Enable the setting of
Overload prevention control
(3008-47 hex).

Prevention
Examine the ambient tempera-
ture of the inverter and provide
the necessary cooling.
Set the value of Torque Boost
Voltage (3004-0A hex, 3009-06
hex) appropriately.
Set the acceleration/deceleration
time as long as possible to re-
duce the load. Or set a longer
stop time to reduce the load.
Select a motor and an inverter
according to the load.
