Electrical switching & drive systems & components
The easy to use positioning system, EPOS, from maxon motors is being expanded to a second generation, the EPOS2 24/2. Several variants permit the use of a range of brushed DC motors with encoder, or brushless EC motors with Hall sensors and encoder up to 48 W.
The EPOS2 24/2 was developed specifically for commanding and controlling in the CANopen network. USB and RS232 are available as further communication interfaces. The various operating modes, such as position, velocity and current mode, allow flexible use in automation technology, tool building and mechatronic drive systems. There are also functions such as Step/Direction Mode for the incrementally controlled movement of the motor shaft or Master Encoder Mode for applying the drive as electronic gearing.
The EPOS2 24/2 features outstanding motion control functionalities. For instance the controls offer a dual loop position and speed controller. In Interpolated Position Mode, the position controller is able to follow a path set by support points synchronously, dynamically and with great precision. During startup, the current, speed or position controls can be set extremely efficiently through the enhanced Regulation Tuning mode.
Commands can be sent through CAN Master using for example EPOS2 P, SPS, Soft SPS, PLC or PC via USB or RS232. Several drives can be networked and coordinated through the standardised CANopen interface. Further integrated gateway functions such as USB to CAN or RS232 to CAN help simplify access to the CAN network.
The EPOS2 24/2 quasi represents the degree of miniaturisation currently possible in positioning controller design, and offers the ultimate in power, functionality and comfort in a small space. The variants are fully compatible with the preceding EPOS 24/1 and can be combined with any controller in the series, namely EPOS2, EPOS, EPOS2 P and EPOS P within a CAN network.
Precise detection of complex rotational movements Beckhoff Automation
Electrical switching & drive systems & components
The EP3751-0260 EtherCAT Box module by Beckhoff connects an acceleration sensor with an inertial measurement unit - a gyroscope. This provides accurate detection of acceleration and rotational motion in addition to shock, vibration and tilt measurement, both as preprocessed values and as raw sensor data.

Electrical switching & drive systems & components
In the machine manufacturing industry, more drive systems are being converted from servo-hydraulic throttle to electrohydrostatic actuation systems. The four-quadrant capability of the electrohydrostatic pump unit and servo drive used in this technology, in combination with the new Moog energy management system, allows regenerative power flows generated during braking or pressure relief to be stored and reused.
