Additional Information

The Siemens 6SN1123-1AA00-0LA1 is a 1-Axis, 45 Amp Power Module in the Simodrive System. It uses a forced cooling method for internal and external heat dissipation. Its total power loss is 460 Watts overall when operating 1FT6, 1FK, 1FN, or 1FW6 motors - 25W from internal power loss and 435W from external power loss. When operating 1PH, 1FE, 2SP1, 1PM, or asynchronous low voltage motors, its power loss is 460 Watts, 19W from internal and 441W from external. Its maximum possible conductor cross section is 50mm².

In order to take into account technical leaps, the drive firmware for the 6SN1123-1AA00-0LA1 has been continually developed over time. Even though firmware is optimized regarding runtime behavior, more recent firmware releases could have a different runtime behavior. This must definitely be taken into account if its functions involve a large level of runtime. When you upgrade the Power Module to a new firmware release, it must be carefully checked and found satisfactory. If you need to, reoptimize the drive settings or do not upgrade the firmware. It is recommended when upgrading firmwares that the latest hardware is also used. Firmware updates can be downloaded using the SimoCom U setting and commissioning tool. Under the menu item “Options / Service / …”, select the required firmware upgrade item and then continue to follow the promptings. For a connection using the Profibus-DP, only an update or download is possible to any of the drive’s firmware status. It is also possible to download the firmware of the Profibus module using a connection through the RS 232 interface. One should never interrupt or exit the update if at all possible. Otherwise, the module will no longer be able to be identified and addressed. An automated firmware download is also possible using the “SimoCom U” tool. This means that the actual firmware and their previous releases can be downloaded. It can be downloaded via the data bus or the serial interface.
