Successful automatic download

After a successful automatic download, F0395 will be displayed.

• In case of a standard CU a confirmation is necessary.

• In the case of CUs with safety integrated functions, an acceptance test must be

performed.

Confirmation

On standard CUs the current parameter set needs to be checked and confirmed by clearing

F0395. It can be cleared via:

• Digital input or PLC signal (depends on the settings of P0700)

• setting P7844 = 0.

Warning

The user is responsible for ensuring that the parameters held in the CU are the correct

parameters for their application.

Acceptance test

On CUs with integrated fail-safe functions it is necessary to do an acceptance test (refer to

the "Safety-Integrated functions" section in this manual). To clear F0395 on CUs with

integrated fail-safe functions the following procedure has to be followed:

• P0010 = 95

• P9761 = fail-safe password

• P7844 = 0

Automatic download fault

If the automatic download process fails, the CU will return to the parameter set previously

held in the EEPROM and the following fault codes are generated:

Table 2-17 Automatic download fault codes

Fault code Description

F0061 Automatic download of parameters was not successful.

F0063 Automatic download of parameters was not successful (e.g. wrong CU).

In this case check, wether the MMC is defective or a parameter set clone00.bin is available

or the parameter set is valid.
