CANopen drives

Providing currents up to 500 A

The Rayon drives from Redler Technologies (Israel) are dedicated for brush-less DC motor control. The devices integrate one CANopen interface respectively.

The CANopen interface supports bit-rates up to 1 Mbit/s; 11-bit and 29-bit CAN-IDs can be used. Comprehensive emergency messages can be sent via the CANopen network. Initialization of the motor and the feedback connections are done automatically.

For example, the 25-A Rayon Slim Line drive offers EIA-232 and EIA-422 interfaces as well several I/Os. It integrates a 100-MHz 32-bit DSP (digital signal processor) with a 256-KiB flash memory and a 32-KiB RAM. The device supports sinusoidal and trapezoid drive functions, one analog/digital Hall primary encoder, and a digital secondary encoder. The PID (proportional integral differential) closed-loop modes include based on position, speed, and current. Esafe Eeprom-based parameter file-system protection is on-board. The drive integrates live graph monitoring functions. Labview load and read parameters can be used. A voltage supply from 16 VDC to 40 VDC is required. Operating temperature range from -55 °C to +71 °C can be extended to +85 °C on demand. Movement control of medium-sized actuators in mobile robots and small real-estate applications are the typical use cases.

The company, which recently joined CAN in Automation (CiA), also offers further CANopen-capable Rayon drives for currents up to 500 A (e.g. for military positioning applications). The smallest drive performed as a PCB (printed circuit board) dimensions 30 mm x 20 mm x 7 mm. Also offered is the Boss main controller for up to 12 drives.
