2. Verify that all Flex I/O modules are installed on their rack in the same
order that they are:
• enabled in the Flex I/O page of the Configure Control Options
dialog box, and
• configured in the Configure Flex I/O Module menu.
3. Restart the controller.
If the problem persists, it is a hardware problem. Return the controller to
the manufacturer for repair.
This fault condition does not appear as an independent fault variable in
either the Tag Window or the Expression Builder.
Insufficient Time (Linear Interpolation)
his fault (Runtime_fault = 28) indicates that a timed linear interpolated
move (set in an Interpolate Axes block with Trapezoidal Profile selected)
failed because:
• the calculated Accel/Decel exceeds the input Accel/Decel, or
• the calculated velocity exceeds the input speed.
Consequently, there is not enough time to move the commanded distance
at the input Speed and Accel/Decel.
To correct the problem:
Increase one or more or the following timed linear interpolated move
settings:
• Time
• Speed
• Accel/Decel.
See the online help topic Timed Linear Interpolation for more
information.
