14.33 PLC Axis Control
bitE: 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 PLC axis control valid
signal to 0, or turning the power OFF then ON again.
Note
(1) When servo alarm occurs, 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
S03 Servo alarm 52
bitF: ALM1 Control information data designation alarm
This bit turns ON when the designated details of the control information data are illegal.
When an alarm occurs for the simultaneous operation of buffering mode and single mode, the mode designated later is
not executed and the mode designated first continues processing.
PLC axis control is not executed when any other alarm occurs.
Turn the bit OFF by correcting the data, outputting a reset signal, or setting PLC axis control valid signal to 0.
Note
(1) The status of the PLC axis, to which the PLC axis control valid signal is ON, is automatically updated.
