Correction
Measure the ambient tempera-
ture.
→ Lower the ambient tempera-
ture.
Check if the motor's cooling sys-
tem is operating normally.
→ Repair or replace the motor's
cooling system.
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.)
→ Lower the ambient tempera-
ture.
→ Increase the Carrier
Frequency (3004-1B hex).
Check the specifications of the
PTC thermistor and recalculate
the detection voltage.
→ Change the parameter data.
Check the value of 1st
Thermistor mode selection
(3008-1B hex).
→ Change the setting of 1st
Thermistor mode selection
(3008-1B hex) to an appropriate
value for the thermistor.
