Part 3 Maintenance
Alarms are classified into two levels based on the symptoms associated.
Alarm level

Lit “1”
After deceleration stop

(RES) from the PLC.

the PC/teaching pendant.

*
The ALM signal uses the positive logic.
After the power is turned on, this signal remains “0” while the system is normal, and turns “1” if an alarm has
occurred.
(Since the signal becomes “0” when the power is cut off, it cannot be used as an interlock signal.)
How to reset operation-cancellation alarms
Input the alarm reset (RES) signal for 6 msec or longer.
The ALM signal will return to “0” after the above period. Confirm the “0” status and then set the RES signal to “0”
(OFF).
Caution
Reset each alarm after identifying and removing its cause.
If the cause of the alarm cannot be removed, or the alarm cannot be reset even after its cause has been removed, contact
IAI.
If the same alarm generates again after a reset, the cause of the alarm has not been removed. In this case, repeating the
reset action may result in a burned motor or other undesired condition. Be sure to identify the cause and remove it before
resetting the alarm.
An alarm list for RACON and RPCON is provided on the next page.
