| The last fault that occurred remains stored in the "Altivar fault code" (LFt) parameter, even if it disappears and even after | |||||
| the drive has been turned off and then on again. |
|
|
| ||
| 0: | (nOF) | No fault |
|
|
|
| 1: |
| Reserved |
|
|
|
| 2: [Control Eeprom] | (EEF1) | Internal memory fault, control card |
| ||
| 3: [Incorrect config.] | (CFF) | Option card changed or removed |
| ||
|
|
| Control card replaced by a control card configured on a drive with a different rating | |||
|
|
| The current configuration is inconsistent |
| ||
| 4: [Invalid config.] | (CFI) | Invalid configuration. The configuration loaded in the drive via the bus or | |||
|
|
| communication network is inconsistent |
| ||
| 5: [Modbus com.] | (SLF1) | Interruption in communication on the Modbus bus |
| ||
| 6: [internal com. link] | (ILF) | Communication fault between option card and drive | |||
| 7: [Com. network] | (CnF) | Communication fault on communication card |
