PacDrive drives

The PacDrive family offers a broad power range. It can handle everything from paper converting to palletizing.

Each motor has a smart chip inside, which the drive automatically recognizes at setup. Feedback is absolute and extremely precise, as required for Gen3 functionalities and beyond.

Intelligent drives perform all the tasks needed for precise motor control. For maximum efficiency, all motion tasks are in the controller. This is why we can run so many drives on a single controller.

The digital MC-4 motor controller is characterized by its compact and independent structure with wall mounting fixtures as well as state-of-the-art technology. The innovative MC-4 has the power supply unit, the power output stage and the software controller for an axis all in one casing, which saves space. As it communicates with the controllers only via fiber-optic cables, it is also suitable for distributed structures. It requires no user program, processes single- or multi-turn encoders in the standard version and configures itself with the help of the electronic type plate in the motor.

Though MC-4 motor controller are optimized for servo motors of the PacDrive SH series, torque and linear motors can be controlled as well, if they are equipped with appropriate feedback technology.
