MMC
The Multi Media Card (MMC) is a small, removable flash storage device, with a low power
consumption which provides the ability to store data sets for the inverter.
The MMC provides non volatile data storage which requires no power to maintain the data
stored on the card.
It is recommended that the SINAMICS-MMC (order number: 6SL3254-0AM00-0AA0) is used
for the storage and transfer of data sets.
Option port
Via the Option port the OP is connected to the inverter, it can also be used to connect a PC
via the PC Connection Kit to the inverter for parameterizing using STARTER.
