Output side earth
(ground) fault
overcurrent
The inverter trips if an earth (ground) fault
overcurrent flows due to an earth (ground)
fault that occurred on the inverter's output
side (load side).
(E.GF)
Ground Fault { { — —
Output side earth
(ground) fault
overcurrent at start
The inverter trips if [ Pr. 249 Earth (ground)
fault detection at start ] is set active (=1) and
an earth (ground) fault overcurrent flows at
start due to an earth (ground) fault that
occurred on the inverter's output side (load
side).

Ground Fault — — { {
External thermal
relay operation
If the external thermal relay provided for
motor overheat protection or the internally
mounted temperature relay in the motor, etc.
switches ON (contacts open), the inverter
output is stopped.
(E.OHT)
OH Fault { { { {
PTC thermistor
operation
For , the fault appears when the
motor overheat status is detected for 10s or
more by the external PTC thermistor input
connected to the terminal AU.
For , inverter trips when resistance of
PTC thermistor connected between terminal
2 and terminal 10 is more than the value set
in [
Pr.561 PTC thermistor protection level ].
(E.PTC)

Option fault
Appears when the AC power supply is
connected to the terminal R/L1, S/L2, T/L3
accidentally when a high power factor
converter is connected.
Appears when the switch for the
manufacturer setting of the plug-in option is
changed.
For , it appears when torque
command by the plug-in option is selected
using [
Pr. 804 Torque command source
selection ] and no plug-in option is mounted.

Communication
option fault
Stops the inverter output when a
communication line fault occurs in the
communication option.

Option3 Fault { — — —
Option fault
Stops the inverter output if a contact fault or
the like of the connector between the
inverter and built-in option occurs or if a
communication option is fitted to the
connector 1 or 2 ( only).
Appears when the switch for the
manufacturer setting of the plug-in option is
changed.
