7.2 Troubleshooting
This section describes the RMU errors which may occur and the action taken to remedy them.
When error occurs, “assist code” is displayed with error code in error message.
Information to identify where trouble happens can be get by this “assist code”.
In the Table 5-1, the error code and the assis code are listed.
Because random number is displayed for the assist code depending on the error code, "-" is used for that.

This error occurs when
something is wrong with the
encoder data for the RMU.

-
This error occurs when
encoder internal failure
occurs.

- -
This error occurs when servo
ON operation is tried with
encoder communication of
some axes are not
established.
Encoder error

E01
When this error has
occurred, power supply
output is turned OFF. The
emergency stop output
depends on the status of the
emergency stop signal.
Check if an error of "E51
Encoder data
transmission error"
occured at the same time.
If it has occured,
encoder wire or the drive
unit may be wrong. Please
check the connection of
the robot internal wiring
and the wire-harness. Or,
repleace the drive unit.
If it has not occured,
please check the wiring to
the RMU. And, check the
setting parameter of
"Encoder type" in the
<Constant Setting> -
[Machine constants]
[Motor & Encoder] menu.
After removing the failure, it is
necessary to turn OFF and
ON the primary power of the
controller.
