MMC
The MMC provides the ability to store parameter sets or firmware versions of an inverter.
It is recommended that the SINAMICS-MMC (order number: 6SL3254-0AM00-0AA0) is used
for the storage and transfer of parameter sets or firmware versions.
Option port
Via the Option port a PC (using the PC Connection Kit) or a BOP is connected to the
inverter. With a PC the inverter can be easily parameterized using the commissioning tool
STARTER.
