SCM compact decentralized controller in multi-axis version

For mobile and decentralized motion and processing tasks

We have tailored the multi-axis servo controller solutions specifically to customer requirements for mobile and decentralized applications in DC 48 V technology.

The SCM compact design with IP20 degree of protection and with two axes is developed specifically for compact installation in a machine. With the version without a through-hole heat sink, assembly and cooling takes place via the cooling plate directly in your machine. Prefabricated cables are available for the electrical connection of the motors. The peripheral connection of the decentralized controller can be configured individually using the "Periphery SCM connector" accessory. The "SCM shield connection" is available for connecting the shield directly to the device.
