Incorrect or out of range axis parameter value
If the value of an axis parameter is incorrect or out of range an axis error
occurs. No alarm or error shows on the display of the Servo Driver assigned
to the axis.
You can see the cause of the error with the AXISSTATUS command. In the
Trajexia Studio terminal window, type PRINT AXISSTATUS AXIS(nn),
where nn is the axis number. The return value of the AXISSTATUS
command contains the axis error code. See the AXISSTATUS command.
You can also open the Axis Parameter window in Trajexia Studio and check
the AXISSTATUS field of the axis that caused the error. The bits that
indicate the cause of the error show in big red letters. To remove the error,
do these steps:
1. Correct the value.
2. Reset the controller, or click the Axis status error button.
Error or alarm on Servo Driver assigned to the axis
If an error or an alarm on the Servo Driver assigned to the axis causes an
axis error, the drive alarm shows on the LED display of the drive. You can
also open the Axis Parameter window in Trajexia Studio and check the
AXISSTATUS field of the axis that caused the error. The return value of the
AXISSTATUS command has the second bit (bit a: Servo Driver
communication error) and/or the third bit (bit m: Servo Driver alarm) show in
big red letters.
To remove the error, do these steps:
1. Refer to the Servo Driver manual to determine the cause of the error,
and solve the error.
2. Reset the controller, or click the Axis status error button in the Axis
Configuration window, Monitoring tab..

The error code U0n shows on the display, where n ranges from 0 to 6 and is
the number of the unit that causes the error.
To solve the problem, check the bus connector of the unit.
I/O unit or Inverter on a MECHATROLINK-II unit is lost or
disconnected
The error code U0n shows on the display, where n is the number of the TJ1-

You can set system flags to enable and disable these errors. The errors are
enabled by default.
To disable the errors, type COORDINATOR_DATA(7,1) in the Trajexia
Studio terminal window.
