CompoBus/D Communications Card Operations | Chapter 5 | |||
|
|
|
| |
Note | 2. | Control From Net shows the input status of word n, bit 5 (Net Control) for CompoBus/D com- | ||
|
| munications. |
|
|
Note | 3. | The Reference From Net and Control From Net functions are applicable for Inverter software | ||
|
| versions S1042 and later. Check the version with the Inverter monitor function | ||
Note | 4. | Reverse Operation indicates reverse output status. This bit does not turn ON for DC braking | ||
|
| (DC injection). |
|
|
Note | 5. | Forward Operation indicates either forward run status or DC braking (DC injection) status. | ||
|
| This bit turns ON even for DC braking (DC injection) during reverse run. |
