Start-up and Swap Behavior of the Inverter

Overview
When starting-up the inverter checks, whether an MMC is plugged in or not.
If it is plugged and no swap has been taken place the start-up runs according the "Normal
start-up behavior". If a component (CU or PM) has been replaced, this is called a swap and
the start-up will be performed according the "Swap behavior" of the inverter.
5.10.1

Normal Start-up Behavior of the Inverter

Description
A normal start-up is a start-up after a power-cycle or a black-out. It can be performed with or
without MMC.
Normal start-up behavior without MMC
After a power-cycle or a black-out the inverter reads the parameters from EEPROM to RAM.
Normal start-up behavior with MMC
The CU detects automatically whether an MMC is present.
The start-up behavior is controlled using P8458 as follows:
P8458 = 0: No automatic parameter download from the MMC.
P8458 = 1: Automatic parameter download from the MMC only once (at the next start-up
P8458 = 2: Automatic parameter download from the MMC (if present) after each start-up
Once the download has been finished, the MMC can be withdrawn. If no MMC is plugged in,
the inverter will start-up with the parameters stored in the EEPROM without an alarm or fault
message, even if P8458 is set to 1 or 2.
Note
MMC for "automatic download"
For an automatic download always the file clone00.bin will be used.
The user has to take care, that clone00.bin (saved as "clone00.bin" with STARTER via PC or
via setting P0804 = 00 with the BOP) is available on the MMC under
/USER/SINAMICS/DATA/clone00.bin, used for an automatic parameter download at start-
up. If clone00.bin does not exist drive will fail with F0064.

any further automatic download of parameters.
