The new Siemens Sinamics S120 AC is now available from Micromech. It expands the existing Sinamics S120 system into an integrated modular drives system for single-axis and multi-axis applications. Depending on the system voltage, the units are rated at 1AC 230 V in the power range 0.12 to 0.75 kW, and at 3AC 400 V in the power range 0.37 to 250 kW. The devices are available in block-style construction (0.12 to 90 kW) or as chassis devices (110 to 250 kW) according to the power rating.
The drives combine components for rectifier and power supply of the motor in one device, the power module – the PM340. As a single-axis drive in combination with a higher-level controller, a control unit CU310 is plugged onto the power module. This contains the entire closed-loop control intelligence, including the fieldbus interface and the positioning functions. The control unit is available optionally with Profibus or Profinet interface. The drive software is stored on a compact flash card and an optional, easy to use operator panel is available if required.
