The Siemens 6SN1123-1AA00-0EA1 is a 1-Axis, 60A Power Module in the Simodrive 611 family of CNC equipment. This power module is graded according to current rating and can be supplied with 3 different cooling techniques. Because of its modular, seamless and space-saving nature, the power module can be used for a variety of solutions, from small, compact machines to complex machining centers and automatic lathes. The power module provides energy to the control boards and the connected motor. It is grounded through PE connecting screws, and must be mounted on a grounded, low-resistance conductive mounting services. Power is fed in through the DC link bus bars. Together with the control module, the 6SN1123-1AA00-0EA1 forms the drive module for a feed or main spindle application.
Its output currents can be limited by the control unit being used. After the control unit has been inserted into the module, the retaining screws on the control unit’s front panel must be tightened in order to retain a good connection with the module housing. The power module is equipped with protections against overloads, and prevents motors and cables from being overloaded when correspondingly dimensioned. The power module can be used with feed drives, such as synchronous motors (servo motors, built-in torque motors, and linear motors). It can also be used with main spindle drives including induction motors (Main spindle motors, hollow shaft motors, and standard induction motors) and synchronous motors (1FE1 main spindle motors and 2SP1 motor spindles). The Siemens 6SN1123-1AA00-0EA1 can be operated with both a regulated and unregulated supply modules that belong to the Simodrive 611 drive system. When using a PH, 1FE1 motor, or induction motor with an unregulated infeed, a lower maximum motor output is available in the higher speed ranges than with the use of a infeed or regenerative feedback module.
