High-function General-purpose Inverter RX2 Series User’s Manual
Errors occurring in an option mounted in the option slot 3 (to the observer’s right) are detected.
For details, refer to the instruction manual provided together with the option mounted.
When there is a path error in functional safety circuit, an inverter outputs the error.
For details about E090 to E093, refer to Section B Appendices B STO Function.
This is an error related to feedback options.
When you set a switch on the PG option unit of feedback options, [E100] encoder disconnection error
can generate the inverter trip.
For the setting procedure, refer to 2-3-6 Wiring for PG Option Unit on page 2-63.
E080 to E089 Option 3 Errors 0 to 9
Occurrence Estimated cause(s) Exemplar measures to be taken
Error occurred when
an option is
mounted.
The option isn’t securely
mounted.
The option may not be securely mounted.
Check the mounting state.
The option is used in the
wrong way.
The type of error varies depending on options. For details,
refer to the instruction manuals provided together with the
respective options.

E100 Encoder Disconnection Error
Error cases Cause Examples of Measures
This error occurred
when turning a
power supply ON.
Error on encoder wiring
or encoder
• Check encoder signal and the wiring.
• Check that there is not any delay when the encoder power
supply rather than inverter one is turned ON and the power
is supplied.
This error suddenly
occurred during the
operation.
Error on encoder wiring
or encoder
Check encoder signals and the wiring.
This error occurred
when cutting off the
power supply.
Or whenever the
power supply was
turned ON, this error
history was added.
Error on a power supply
inside inverter or an
encoder power supply
• Check that inverter failure or overload of the encoder power
supply.
• Check that there is not power loss on the encoder power
supply rather than the inverter one when you use the
encoder power supply.
