Azionamenti e motori Heidenhain

The Heidenhain UM 111 is a specialized electronic module that serves as a core component in Heidenhain drive systems, which are widely used in high-precision Computer Numerically Controlled (CNC) machine tools. In technical terms, this product is most often described as a power module (Leistungsmodul), frequency converter (Umrichter), or servo drive.Its primary function is to control and power a single electric motor. This motor can be either a feed axis motor (responsible for movement along the X, Y, or Z axis) or the machine's main spindle motor. The UM 111 is part of a larger, modular Heidenhain drive system, designed to work in conjunction with supply units (e.g., from the UV or UVR series) and controller units (CC).Key Features and Characteristics:Power Conversion: The UM 111 module converts DC voltage from the drive system's intermediate circuit into a three-phase AC voltage with variable frequency and amplitude. This allows for precise control over the motor's rotational speed and torque.Modular Design: Heidenhain drive systems, including the UM series, feature a modular design. This means that several specialized modules are installed side-by-side in the machine's control cabinet—one supply module and a corresponding number of power modules (like the UM 111) for each controlled axis and spindle.Product Variants: Several versions of the module exist on the market, differing in their specifications and intended use. For example:UM 111B / UM 111BD: These versions may differ in their rated current, such as 15A for an axis or 20A for a spindle. The "D" suffix might indicate a newer revision or additional features.Different identification numbers (ID) point to specific hardware variants and revisions.

The Heidenhain UM 116DW inverter is a power module designed for use with one axis or one spindle in industrial automation systems. It is intended for applications that require reliable power handling together with integrated diagnostic functions and an electronic ID label for easier identification and service support.The module is built for demanding drive tasks where efficient thermal management is essential, using externally water-cooled heat removal to support stable operation under load. It also includes a connection for holding brakes, making it suitable for motion systems that require secure load retention. The available technical data indicates a rated current of 150 A for axis use or 210 A for spindle use at 5 kHz, with a maximum current of 300 A.With its compact module width and service-oriented design, the UM 116DW supports integration into advanced drive architectures where monitoring, performance, and maintenance efficiency are important.
