Siemens 6SN1118-0DG23-0AA1 Overview

The drive module 6SN1118-0DG23-0AA1 is manufactured by Siemens as a part of the SIMODRIVE group of modular units.  The 6SN1118-0DG23-0AA1 is a digital 1-axis control module. It is a power drive control module providing the necessary energy supply for the control boards and any connected motor. The control board and the motor inform the selection of the correct power module. These products are manufactured in Germany and are designed for Automotive, aerospace, power generation, and electronics usage. They come with a 2-year warranty from MRO Electric. We also carry AC Drives from other manufacturers such as FANUC and Yaskawa.


The Siemens 6SN1118-0DG23-0AA1 works with the closed-loop control 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 Siemens 6SN1118-0DG23-0AA1 1-axis control unit is made for digital drives, and feed and main spindle drives. It is used with drive software which is downloaded in the initiation phase where the power supply is either in or in reset. It is downloaded from the SINUMERIK 840C or 840 D into the control module. It does this by way of the drive bus. This 1-axis performance module is used to operate specific motors. Which motors are this module manufactured to operate? Motors 1FT6/1FK6/1FN1/1FE1 and 1PH are the motors operated by the Siemens 6SN1118-0DG23-0AA1.

Can the Siemens 6SN1118-0DG23-0AA1 be loaded with drive software for feed drive? Yes, the 6SN1118-0DG23-0AA1 can be downloaded with drive software for not only feed drive but also main spindle drive control. Is the operator interface the same for both MSD and FD? It is the same for both.

There are two analog inputs as well as two analog outputs on the digital 1-axis control module. It also has 2 test sockets. The data and software are stored on a memory module. The memory module can be changed.


The Siemens 6SN1118-0DG2_ has three different versions available. The first version of the 1-axis drive control module is the basic version. The basic version includes sinusoidal voltage signals. It is capable of connecting absolute encoders with the EnDat interface. The second version of the Siemens 6SN1118-0DG2_ is the same as the first with the addition of the ability to evaluate a direct position measuring system with sinusoidal current signals. The third version of the Siemens 6SN1118-0DG2_ has both the advantages of the first two versions along with the possibility of connecting absolute value encoders with the EnDat interface an SSI interface.
