12 - 12 High-function General-purpose Inverter RX2 Series User’s Manual
When the inverter accepted a signal commanded by an external device or equipment, the inverter turns
OFF its output. (When external trip function is selected.)
This error occurs if an operation command has been input to the inverter when the power supply is
turned ON. Operation command detection is carried out for 1 second after the power supply is turned
ON. (When USP function is selected.)
This is a function to protect the inverter by the detection of ground faults between the inverter output
and the motor at power-on.
The function doesn’t work when there is a voltage induced in the motor due to idling or when the
inverter trips.
When the control circuit power (R0, T0, or 24 V power supply) has been turned ON prior to the main cir-
cuit power R, S, or T, the function is activated at the time the main circuit power is turned ON.
Setting the ground fault detection selection [bb-64] to 00 disables the ground fault function. Setting it to
01 enables the function.
E012 External Trip Error
Occurrence Estimated cause(s) Exemplar measures to be taken
Error occurred unin-
tentionally.
• Terminal logics are
reversed.
• Wiring is wrong.
• You need to check the state of operations related to external
devices or external equipment, and re-examine the assign-
ment of external trip terminal to the inverter input terminal,
the setting of a/b contact, the external trip command via
communication, etc.
• A/b contact of terminal can be changed by inverter setting.
E013 USP Error
Occurrence Estimated cause(s) Exemplar measures to be taken
Error occurred unin-
tentionally.
Operation command was
entered too early.
Re-examination of the sequence to enter operation command
is required. You need to wait for 2 seconds or longer to enter
operation command after turning ON the power supply.
Operation command isn’t
released. You need to release an operation command when turning ON
the power supply.
You tried to operate with
commands other than
terminal commands.
When USP is enabled, commands of the operator keypad and
communication commands are treated as errors. You need to
wait for 2 seconds or longer to enter operation command after
turning ON the power supply.
E014 Ground Fault Error
Occurrence Estimated cause(s) Exemplar measures to be taken
Error occurred as
the power supply
was turned ON.
• Ground faults of wires
or the motor
• Motor insulation deteri-
oration
• Turn OFF the power, remove the wires connected to the
motor, and then check the motor and the wires. A ground
fault may have been occurred.
• Turning ON the power supply in a ground fault state results
in a failure. Do not turn ON the power when you check the
motor and motor wires.
