Copley Controls: Accelnet Plus Panel, 2-Axis (BP2 Series)

14-90V VDC CANopen Drives for Brushless Motors

Description

The BP2 is a high-performance, DC powered drive for position, velocity, and torque control of brushless and brush motors via CANopen. Drive commissioning is fast and simple using CME 2™ software operating under Windows® and communicating with the BP2 via RS-232.

The BP2 operates as a CANopen DS-402 node. Supported modes include: Profile Position-Velocity-Torque, Interpolated Position mode (PVT), and Homing.

Feedback from both incremental and absolute encoders is supported. A multi-mode encoder port functions as an input or output depending on the drive’s basic setup. As an input, it takes feedback from a secondary encoder to create a dual-loop position control system or as a master encoder for driving a cam table. As an output, it buffers the digital encoder signals from the motor’s digital encoder and eliminates split cables that would be needed to send the signals to both drive and control system.

There are ten non-isolated inputs. eight opto-isolated digital inputs are bipolar types that source or sink current into a common connection that can be tied to ground or +24V. [IN1&10] default to the drive enable function for axes A & B, and are programmable to other functions. The other inputs are programmable. all inputs have programmable active levels. five opto-isolated outputs [OUT1~5] have individual collector/emitter connections. Two MOSFET outputs [OUT6~7] are programmable to drive motor brakes or other functions.

Drive power is transformer-isolated DC from regulated or unregulated power supplies. an AuxHV input is provided for “keep-alive” operation permitting the drive power stage to be completely powered down without losing position information, or communications with the control system.
