It operates as a distributed drive using the CANopen protocol, or as a stand-alone drive accepting analog or digital commands from an external motion controller. In stand-alone mode, current and velocity modes accept digital 50% PWM or PWM/polarity inputs as well as ±10V analog. In position mode inputs can be incremental position commands from step-motor controllers, analog ±10V, or A/B quadrature commands from a master-encoder. Pulse to position ratio is programmable for electronic gearing. Accelnet R20 models operate as Motion Control Devices under the DSP-402 protocol of the CANopen DS-301 V4.01 (EN 50325-4) application layer. DSP-402 modes supported include: Profile Position, Profile Velocity, Profile Torque, Interpolated Position Mode (PVT), and Homing. The two CAN ports are optically isolated from drive circuits. There are twelve digital inputs eleven of which have programmable functions. These include CAN address, motion-abort, limit & home switches, stepper/encoder pulse inputs, reset, digital torque or velocity reference, and motor over-temperature. Input [IN1] is dedicated for the drive Enable. There are three programmable logic outputs for reporting an drive fault, motor brake control, or other status indications. Drive power is transformer-isolated DC from regulated or unregulated power supplies. An AuxHV input powers control circuits for “keepalive” operation permitting the drive power stage to be completely powered down without losing position information, or communications with the control system.

Accelnet R20 RUGGEDIZED DIGITAL SERVO DRIVE FOR BRUSHLESS/BRUSH MOTORS R20 RoHS COMMUNICATIONS CME 2 SOFTWARE Drive setup is fast and easy using CME 2 software communicating via RS-232 or over the CAN bus. All of the operations needed to configure the drive are accessible through this powerful and intuitive program. Autophasing of brushless motor Hall sensors and phase wires eliminates “wire and try”. Connections are made once and CME 2 does the rest thereafter. Encoder wire swapping to establish the direction of positive motion is eliminated. Motor data can be saved as .ccm files. Drive...

Accelnet R20 RUGGEDIZED DIGITAL SERVO DRIVE FOR BRUSHLESS/BRUSH MOTORS R20 RoHS COMMUNICATIONS (CONTINUED) CANOPEN Based on the CAN V2.0b physical layer, a robust, two-wire communication bus originally designed for automotive use where low-cost and noise-immunity are essential, CANopen adds support for motion-control devices and command synchronization. The result is a highly effective combination of data-rate and low cost for multi-axis motion control systems. Device synchronization enables multiple axes to coordinate moves as if they were driven from a single control card. CANOPEN...
