Condition Possible cause
Rotation Direction Limit Selection
(b035) is set and forward or
reverse rotation is prohibited.
The input terminal wiring
for RUN command or
shorting-bar connection
position is incorrect.
The analog input for
frequency reference or
Variable Resistor wiring is
incorrect.
"51: F-TM (Forced terminal
block)" is allocated to a
multi-function input terminal
and the terminal is turned
ON, even though a Digital
Operator mode is selected.
"31: OPE (Forced
operator)" is allocated to a
multi-function input terminal
and the terminal is turned
ON, even though the
control circuit terminal block
mode is selected.
The Inverter has tripped.
(The ALARM LED
indicator is lit and "Exxx"
is shown).
The safety function
selector switch is turned
ON and the multi-function
input terminal S3/GS1 or

Remedial actions
Set the correct Rotation Direction Limit
Selection (b035).
Implement wiring correctly. (The ON/OFF
status of the input terminal can be checked
with Multi-function Input Monitor (d005)).
Implement wiring correctly.
• For the analog voltage or Variable
Resistor input, measure the FV-SC
terminal voltage using a tester, etc. to
check if the correct voltage is output.
• For the analog current input, disconnect
the wiring and measure the source-FI
terminal current using a tester, etc. to
check if the correct current is supplied.
Turn OFF the terminal to which the
applicable function is allocated.
Turn OFF the terminal to which the
applicable function is allocated.
Press the STOP/RESET key to reset the
trip, identify and remove the cause of the
trip based on the error code, and then
restart the operation.
If the safety function is used, turn both the
safety inputs GS1 and GS2 ON. If the
safety function is not used, turn OFF the
selector switch.
Turn OFF the terminal to which the
applicable function is allocated.
Turn ON the terminal to which the
applicable function is allocated.
Check the wiring.
Reduce the load.
Unlock the motor.
