14.1 Error and warning details

(1) Errors
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
Types of errors
Errors detected by the AD75 include parameter setting range errors and errors at
the operation start or during operation.
(1) Parameter setting range errors
The parameters are checked when the power is turned ON and at the rising
edge (OFF ON) of the PLC READY signal [Y1D]. An error will occur if there
is a mistake in the parameter setting details at that time.
When this kind of error occurs, the AD75 READY signal does not turn OFF.
To cancel this kind of error, set the correct value in the parameter for which
the error occurred, and then turn ON the PLC READY signal [Y1D].
(2) Errors at the operation start or during operation
These are errors that occur at the operation start or during operation when
using positioning control, JOG operation, manual pulse generator operation,
etc. If an axis error occurs during interpolation operation, the error No. will be
stored in both the reference axis and the interpolation axis.
Note that in the following cases (a) and (b), the axis error No. will only be
stored in the reference axis during analysis of the positioning data set in each
point of the positioning start data table.
(a) When the interpolation axis is BUSY
(b) When the error occurred in positioning data or parameters unrelated to
interpolation control.
If the error occurred at the simultaneous start of a positioning operation, the
axis error storage details will differ depending on whether the error occurred
before or after the simultaneous start.
•
If the error occurred before the simultaneous start (illegal axis No., other axis
BUSY, etc.), an "error before simultaneous start" will occur.
•
If the error occurred after the simultaneous start (positioning data error,
software stroke limit error, etc.), an error code corresponding to the axis in
which the error occurred will be stored. Because a simultaneous start cannot
be carried out due to this, a "simultaneous start not possible error" error code
will be stored in all axes in which an error has not occurred.
The axis operation status will be displayed as "error occurring" for axes in
which an error occurred.
If an error occurs during operation, any moving axes will deceleration stop,
and their operation status will be displayed as "error occurring".
Both axes will decelerate to a stop during interpolation operations, even if the
error occurs in only one axis.
