The Bosch Rexroth VT-MAC8-1X/K-AM4 (R901075730) is a state-of-the-art digital multi-axis NC control designed for sophisticated automation tasks. This modular system begins with a master card that can operate independently or be expanded with up to seven slave cards, each capable of managing four axes. As a result, it can handle complex control operations with up to 32 interpolatable axes, making it an ideal solution for demanding motion control applications. The VT-MAC8-1X/K-AM4 offers high flexibility and connectivity through local Ethernet, allowing multiple MAC units to be networked together for coordinated control across numerous axes. Communication with the overarching PLC machine control is facilitated via established fieldbuses such as PROFIBUS DP or CAN, as well as through Ethernet for seamless integration into various industrial environments. Moreover, the system boasts special hydraulic control characteristics that enable it to perform automatic motion control of machines or machine components with precision. It can also take on PLC functions when required, adding to its versatility. The capability of analyzing and activating sensors and actuators over the CAN bus further enhances its functionality, ensuring comprehensive management and monitoring of connected devices. In summary, the Bosch Rexroth VT-MAC8-1X/K-AM4 offers robust and flexible control options for complex automation systems requiring precise coordination of multiple axes. Its modular design and extensive connectivity options make it a powerful component in advanced industrial settings where reliability and performance are paramount.

System overview

technical illustration-R901075730-The MAC8 is the digital Rexroth multi-axis NC control in modular design. It consists of a master card with no, 2 or 4 axis controllers and can be extended with up to seven slave cards for four axes each, if necessary. It is thus the perfect solution for complex control tasks with up to 32 interpolatable axes. Using local Ethernet, more MAC8 can be connected. The MAC8 communicates with the superior PLC machine control via field bus (PROFIBUS DP or CAN) or via Ethernet. It has special hydraulic control characteristics and is able to control the movements of the machine or machine parts in a completely automatic manner and can thus also accept PLC tasks. Sensors and actuators can also be analyzed and/or activated via CAN bus.
