The inverter trips if an earth (ground) fault
Output side earth
overcurrent flows due to an earth (ground)

side (load side).
The inverter trips if [Pr. 249 Earth (ground)
fault detection at start] is set active (=1) and

output is stopped.
For

motor overheat status is detected for 10s or
more by the external PTC thermistor input

operation
For , inverter trips when resistance of

2 and terminal 10 is more than the value set
in [Pr.561 PTC thermistor protection level].
