Description
- The requested product is no longer in our current series product portfolio and is only available to existing customers for a limited time. We recommend using the MLC+H controller family as an alternative for previous applications with the MAC-8.
For further information, please contact us.
Features
- 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.
