Cause and
correction
Assumed cause Correction Prevention
(1) The characteristics of the
electronic thermal and the over-
load characteristics of the motor
do not match.
Check the motor characteristics.
→ Review the values of 1st
motor electronic thermal
overload protection mode
(3004-0B hex) and 1st motor
electronic thermal time
constant (3004-0D hex).
→ Use an external thermal relay
.
Set the parameters according to
the motor characteristics.
(2) The operation level of the
electronic thermal is not appro-
priate.
Recheck the motor
’s continuous
allowable current.
→ Review and change the value
of 1st Motor Electronic
Thermal Level (3004-0C hex).
Set the electronic thermal’s oper-
ation level appropriately.
(3) The acceleration/deceleration
time is short.
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 Acceleration Time 2
(3005-0D hex), 1st Deceleration
Time 1 (3004-09 hex), and 1st
Deceleration Time 2 (3005-0E
hex).
Set the acceleration/deceleration
time as long as possible to re-
duce the load. Or set a longer
stop time to reduce the load.
(4) The load is large. Measure the output current.
→ Reduce the load. (Use 1st
Overload Early Warning
Detection Level
(3005-26 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.)
Select a motor and an inverter
according to the load.
