Maxon (www.maxonmotorusa.com) is proud to announce its expanded EPOS (“Easy to use Positioning System”) for its second generation. The brushless EC motors with Hall encoders and sensors or the EPOS2 70/10 drives DC brush motors with encoders, from five to 700 watts power.

The new unit is packed with a broad range of features and functions and it can handle a multitude of operational modes (“Current Mode, Velocity, Position and others”), thus allowing flexible employment of drive systems in mechatronics and automation. Among the functions is the Master Encoder Mode for the drive’s utilization in electronic gearing applications or Step/Direction Mode for step-by-step movement of the motor (“as a replacement for a stepper motor”). Commanding through an analog set value voltage can replace conventional servo amplifier applications.

The EPOS2 70/10 has high-precision motion control functionality. For instance, the controller offers a dual loop position and speed controller. It means that the load is controlled directly, extremely and precisely with an additional sensor, thus elasticity and mechanical play can be compensated for. Because of the Interpolated Position Mode (“PVT”), the EPOS2 positioning drive has the capability to synchronously run a path specified by interpolating points with high accuracy and great dynamics.

When commissioning, Regulation Tuning allows an extremely efficient adjustment of position regulation, current or velocity. Its integration into the EPOS Studio, a graphic user interface, allows fast parameterization.

The unit is controlled by means of a CAN Master (“for example EPOS2 P, programmable logic controller, Soft PLC”) or with PC through RS232 or USB. Its standardized CANopen interface allows coordination and integration of several drives. Moreover, integrated gateway functions (“RS232-to-CAN, USB-to-CAN”) facilitate access-to-CAN frameworks.
