• Gear Axes
• Time Lock Cam

For example: In a diagram with multitasking, a fault in Task0 might lead
to a fault handling routine which turns off feedback, while Task1
continues to execute and commands motion.
To correct the problem:
1. Turn feedback ON for the necessary axis, using a Feedback block.
2. Re-execute the command.
This fault condition does not appear as an independent fault variable in
either the Tag Window or the Expression Builder.
Illegal Command With Feedback ON
This fault (Runtime_fault = 16) indicates that, because feedback to the
axis is ON, changes to the following data bits (ordinarily made with a
Control Settings block set to Adjust Type) cannot be made:
• Encoder Polarity (B10)
• Servo Output Polarity (B11)
To correct the problem:
1. Turn feedback OFF for the necessary axis, using a Feedback block.
2. Re-execute the Control Settings block.
This fault condition does not appear as an independent fault variable in
either the Tag Window or the Expression Builder.
RIO Fault Code
RIO_fault_code is an integer value representing the most recent RIO fault
condition.
