A self-diagnosis error
above 20
occurs.
KEY POINTS
• When an error with a code above 43 occurs, press the [Clear Error] button
in the status display dialog box to clear the error status. In PROG mode,
connecting to power supply again also can clear an error. However,
contents of the computation memory except data for keeping will be cleared.
When a computation error (code 45) occurs, the address in which an error
•
occurred is saved to special data register DT90017 and DT90018. Before
resolving the error status, click the [Computation Error] button in the dialog
box and view the address in which an error occurs.
REFERENCE
• For how to handle the position control error (error code 44), see "Chapter 19
Error/Warning Annunciation Function".
