CHAPTER 6 COUNTERMEASURE FOR ABNORMALY
6.1 Trip display
When the inverter is in a tripped state, the inverter displays an error code (See table below). The trip history monitor (d081 to d086) also displays the same error code as the inverter.
Trip code | Inverter’s running condition of trip detected |
6.2 Protection function list
The table below describes an error code for protecting the inverter and the motor.
Error Display in the table below, X is 6 (Error for option slot 1) or 7 (Error for option slot 2).
No. | Function | Error | Action |
|
| Display |
|
1 | Profibus communication | EX0 | This error is displayed, when disconnection occurred, while |
| error |
| the inverter is operating with Profibus. |
2 | Inverter communication | EX9 | This error is displayed, when communication timeout occurs |
| error |
| between the inverter and the option board. |
With regard to the other errors except table above, refer to Inverter instruction manual chapter 4 Explanation of function.
6.3 Countermeasure for a trip state
The table below only corresponds to additional trip codes, with regard to the other countermeasures refer to Inverter instruction manual chapter 4 Explanation of function.
