Compact powerhouses with integrated intelligence

SCHUNK has further developed the modules of the second PowerCube generation, placing greater focus on heavy-duty use in industry.

11-26-2013 - On the basis of our experience with the first PowerCube generation, which has been successfully used in laboratory, research, and industry applications, SCHUNK has further developed the modules of the second PowerCube generation, placing greater focus on heavy-duty use in industry. With the PR 2, PDU 2 and PSM 2 high-performance rotary modules, SCHUNK, the competence leader for clamping technology and gripping systems, has expanded its mechatronic program with three especially compact drives with compact performance. All regulating and power electronics have also been fully integrated into the new modules. This saves the need for an external controller, minimizes the cabling necessary and reduces susceptibility to errors.

Fast and simple commissioning

Equipped with standardized plug connections, the modules can be quickly and easily connected. Control can be provided via Profibus (up to 12 Mbit/s) or CAN-Bus (up to 1 Mbit/s). For commissioning and parameterization via PC with the SCHUNK Motion Tool, the modules have a USB device connection. Addressing is done manually via an easily configurable rotary encoding switch. Initial module movements can be realized manually via a DIP switch. The status of each module can be seen on an LED display. Due to Harmonic Drive gears, the PR 2, which was designed as a rotary module, and the PDU 2, conceived as a linear axis drive, achieve very high torques of between 16 Nm and 184 Nm, depending on the size. For fast movement of small masses, the direct-driven PSM 2 can be used. At a torque of up to 0.7 Nm, the compact module achieves speeds of up to 4,800 rpm. Position, speed and torque can be individually controlled on all three modules. An increment encoder ensures high positioning and repeat accuracy. Positions approached can be reliably secured via an integrated holding brake. Two digital inputs have been provided for the evaluation of sensor signals.
