Copley Controls: Accelnet Plus Panel EtherCAT, 1-Axis (BEL Series)

14-90V VDC EtherCAT Drives for Brushless Motors

Description

The BEL is a high-performance, DC powered drive for position, velocity, and torque control of brushless and brush motors via EtherCAT, an Ethernet-based fieldbus. The BEL operates as an EtherCAT slave using the CANopen application protocol over EtherCAT (CoE). Supported modes include: Profile Position-Velocity-Torque, Cyclic Synchronous Position-Velocity-Torque, Interpolated Position Mode (PVT), Homing, and CSTCA (Cyclic-sync torque with commutation angle).

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.

There are seven non-isolated inputs. All inputs have programmable active levels. Three opto-isolated outputs [OUT1~3] have individual +/- connections. An isolated MOSfET brake output [OUT4] is programmable to drive motor brakes or other functions and has a flyback diode to the Brake 24V input for driving inductive loads. 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.
