3. Implementation of the communication option cards
Option card fault
The [internal com. link] (ILF-) fault appears when the following serious problems occur:
- Hardware fault on the option card
- Dialog fault between the option card and the drive
The
[Internal link fault 1] (ILF1) diagnostic parameter can be used to obtain more detailed information about the origin of the last
[internal com. link] (ILF) fault:
This parameter can be accessed on the graphic display terminal only, in the
[1.10 DIAGNOSTICS] (DGt-) menu, [MORE FAULT

(AFI-).
• When the External Fault function is used via a communication card, the Altivar 38 would display EPF, but the Altivar 61 now displays
EPF2.
• When the Fast Stop function is used via a communication card, the Altivar 38 would display RDY, but the Altivar 61 now displays FST.
• It is essential to follow the Altivar 38 internal variables manual when the Altivar 61 is being used in 8 serie mode. If not, migration may
not proceed smoothly.
