It is a 2-axis power module providing high -standard control to any connected motor. The control board and the motor inform the selection of the correct power module.


The Siemens 6SN1118-0DM33-0AA2 is a digital control module. It is used in the SIMODRIVE power module. 

It features a mounting slot for an optional terminal module and a slot for an optional PROFIBUS DP module. There are also front mounting slots for interfaces, terminals, switches, and equipment buses. 

The 2-axis control unit is made for digital drives, and feed and main spindle drives. The Siemens is manufactured to work with the following motors: 1PH/1PM/1LA or 1FT6/1FK/1FE1/2SP1 motors. This 2-axis high-standard version is for motor encoders and offers additional measuring systems as well as voltage signals. A 2-axis module can be used as a 1-axis power module if need be, for single axis applications. If using as one axis, it is engineered as a one axis board. 


The following software releases of the Siemens drive component can be used with the 6SN1118-0DM33-0AA2 digital control module: NCU version:≥ 6.4.9, drive version: ≥ 6.5.4, PCU50/PCU20: ≥ 6.2.18, Commissioning tool for the PC: ≥ 6.2.18, NCU hardware: ≥ 573.3; ≥ 572.3; 571.3, Mixed operation, FD/MSD: ≥ 6.2.12.
