Method 1: Use NIMstudio software to view the motor's historical alarms and current alarms:
1. Open the "Console -> Fault Log" interface in the debugging software.
2. Click "History Alarm" to view the motor's alarm history.
3. Click "Clear History Alarm" to save the alarm information that represents the motor's current alarm.
Method 2 - Using a message to read the current motor alarm:
1. Send a message to read the error code address 603F (037F):
| CANopen | 601 40 3F 60 00 00 00 00 00 |
| Modbus | 01 04 03 7F 00 01 |
2. Identify the alarm by referring to the table below:
