Note 1. Deactivate the alarm about 30 minutes of cooling time after removing the cause of occurrence.
2. In some controller communication status, the alarm factor may not be removed.
3. Alarms and warnings are detected in the following axes.
Each axis: Alarms and warnings are detected in the A-axis and the B-axis separately.
Common: Alarms and warnings are detected in the A-axis and the B-axis together.
4. When an alarm or a warning occurs, the axes stop as below.
Each axis: Only the axis that detected the alarm or warning stops.
All axis: All axes stop.
5. The method is for enabled dynamic brake.
DB: Dynamic brake deceleration
EDB: Electronic dynamic brake deceleration
FR: Coasting
6. When an alarm or warning occurs during servo-on, the deceleration method will be electronic dynamic brake.
7. When Regenerative transistor error (30.2) or Regenerative transistor feedback data error (30.3) occurs, it will be FR.
8. When Overcurrent detected at hardware detection circuit (during operation) (32.1) or Overcurrent detected at hardware detection
circuit (during a stop) (32.3) occurs, it will be FR.
