Fault display
Probable cause and remedy
Data Invalid
(Motor setting data fault)
There was a fault in the data set during auto-tuning.
•
There was a fault in the relationship between the rated frequency, rated
speed, and number of poles.
→
Change the settings to conform to the following formula:
Rated speed < 120
×
Motor frequency/Number of poles
ALARM: Over Load
(Excessive load during auto-tuning)
The effective load factor exceeded 20% during auto-tuning.
•

→
Remove the load.
•
There was a setting fault during auto-tuning.
→
