[Cause]
After the robot controller commanded servo power-off to the local stop unit, the local stop unit status confirmation signal (input signal 1) did not turn on (timeout). The number in parentheses indicates the motion group number.
[Countermeasure]
1. Check that the I/O port type and number are set correctly in the system variables.
2. Check whether input signal 1 actually turned on immediately after this alarm was issued. If it is on, set system variables $LS_CONFIG.$SDI_ON_LAG and $LS_CONFIG.$SDI_OFF_LAG to appropriate values. Do not change these system variables if input signal 1 remains off.
3. When this alarm occurs, LSTP-012 described later occurs at the same time. To clear the alarm state, cycle the controller power once.
4. Check that the hardware wiring is correct.
5. Possible hardware failure. Changed or consulted with my company.
