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..
