bit 8: oper Option error
This bit turns ON when an attempt is made to execute PLC axis control when there is no PLC
axis control option.
bit E: ALM2 Axis in control alarm
This bit turns ON when an alarm occurs (such as a servo alarm) during execution of axis control.
Axis control cannot be executed while this bit is ON.
After the cause of the alarm has been removed, turn the bit OFF by outputting a reset signal,
setting ACT to 0, or turning the power OFF then ON again.
(Note) When alarms occur during axis control, the same alarms appear in the screen as for NC
control axes. Set the PLC 1st axis to "1", and the PLC 2nd axis to "2".
Example: When a servo alarm occurs for the PLC 1st axis

bit F: ALM:1 Control information data designation alarm

the PLC axis control process is not executed. Turn the bit OFF by correcting the data, outputting
a reset signal, or setting ACT to 0.
