Note
When making use of this download procedure, you must bear in mind the following important
constraints:
During the download procedure, the frequency converter will not be able to respond to
any commands.
Once the download procedure is under way, there is no way of stopping it again.
If the data being downloaded are incompatible with the frequency converter, the relevant
parameters in the frequency converter's memory will revert to their default values.
In the event of an unsuccessful download, the frequency converter will not function as it
should.
The LEDs should flash when parameters are downloaded from an MMC to the frequency
converter's EEPROM. However, if the frequency converter is in fault status, this will be
afforded higher signaling priority by the LEDs than the download process. In such an event,
there is no way of knowing whether or not the parameter set has been downloaded correctly.
Manual download
In the case of a manual download, all the necessary parameters (with the exception of fail-
safe parameters) will be downloaded to the frequency converter.
Prerequisites
The download frequency converter's power supply must be connected.
The download frequency converter must be in the "Ready" state.
You must have an MMC, type 6SL3254-0AM00-0AA0, at your disposal.
Procedure
Parameters Description (Parameter name and default setting (if this does not vary) in bold) Setting
Disassemble frequency converter, insert MMC into rear of frequency converter and re-
assemble frequency converter; then perform a manual download.
P0010 = 30 Commissioning parameter*
0: Ready
1: Quick comm.
2: Frequency converter
30: Factory setting, parameter transfer
95: Commissioning of fail-safe functions
P0804 = … Select clone file (for download)
0: clone00.bin
99: clone99.bin
P0803 = 2 Transfer data to EEPROM
0: Disabled
2: Start MMC transfer
If the download was successfully completed, P0010 and P0803 are set to 0 and the "RY/RDY"
LED is lit.
Remark: It is possible to transfer data from one MMC to another using a commercially
available card reader.
An unsuccessful download is signaled by an error message.
