Commissioning

5.5 Commissioning using the BOP

Control Units CU240S

Operating Instructions, 10/2007, A5E00766042B AC

When a parameter is modified, the relevant value is transmitted to the relevant processor in

the CU. The value is transmitted back to the user interface and can be checked by the

processor and the user for correctness.

To complete commissioning of fail-safe functions use setting P3900 = 10, which accepts all

the changes to the fail-safe parameters. All values stored on both processors are checked

and if no discrepancies are found the inverter state will change from "safety commissioning"

to "ready".

If, however, a discrepancy is found safety commissioning can not be finished. The fault

number will be shown in r0947. In this case interrupt the safety commissioning with P3900 =

11 to reload to the former stored settings. To reset all fail-safe parameters to their default

values perform a factory reset of fail-safe parameters with P0970 = 10.

It is also recommended to perform a factory reset of fail-safe parameters with P0970 = 10, if

a fault has been made during safety commissioning, and the system is in an undefined state.

When changing fail-safe parameters, each parameter will be written to the P1 processor and

its equivalent parameter to the P2 processor, for example:

● P9603 selects the required safe digital input terminals or PROFIsafe communications for

P1 processor.

● P9803 selects the selection of the required safe digital input terminals or PROFIsafe

communications for P2 processor.

Example Select PROFIsafe communication:

To select the PROFIsafe communications, following has to be set:

1. P9603 = 128.

2. The system reads the change and processes the information to the drive processor

memory and verifies that the information has been received correctly.

3. P9803 = 128.

4. The system reads the change and processes the information to the communication

processor memory and verifies that the information has been received correctly.

5. Once both write actions have been verified by the system, a checksum is created.

When commissioning has been completed, a checksum for all the data held in both

memories is created and continually checked to verify the integrity of the data.

NOTICE

Behavior of inverter on completion of commissioning

The following behavior should be noted when commissioning the inverter:

• After commissioning the fail-safe functions the fail-safe parameters are automatically

stored in the RAM and EEPROM.

• If an MMC is plugged into the CU, this is not affected by normal commissioning or

commissioning the fail-safe functions.

• To save the EEPROM content on an MMC, an upload from the inverter to the MMC has

to be performed.

• After commissioning the fail-safe functions, an acceptance test must be carried out.
