Operational performance of the converter
Description
A normal power-up procedure refers to the converter starting up after it has been switched
off and on again, or after a power failure. It can be performed with or without an MMC.
Normal startup without MMC
Following a load cycle or a power failure, the frequency converter reads the parameters from
the EEPROM into the RAM.
Normal startup with MMC
The frequency converters have been designed so that they can automatically detect whether
an MMC is available. The level of interaction between the frequency converter and the MMC
is controlled by parameter P8458.
Possible settings for P8458 and its functions are specified below.
P8458 = 0:
Parameters not automatically downloaded from the MMC.
P8458 = 1:
Parameters automatically downloaded from the MMC once (when frequency converter
next powers up (factory setting)). After the download, P8458 will be set to 0.
P8458 = 2:
Parameters automatically downloaded from the MMC (if available) each time the fre-
quency converter powers up.
Once the automatic download is complete, parameter P8458 will be set to 0 (provided that it
had the value 1 before the download), thereby disabling any other automatic parameter
downloads.
If parameter P8458 is set to 1 or 2 and no MMC is available, the converter begins with the
EEPROM parameters without messages or fault codes.
Cyclic data exchange during operation
The frequency converter is controlled via the fieldbus by means of cyclic data traffic. The
frequency converter receives control commands and the frequency setpoint by way of
standard telegram 1.
