Copley Controls: Accelnet Micro Panel (ACJ-090 Series)

20-180 VDC Digital Drives for Brushless Motors

Description

Accelnet Micro Panel is a compact, DC powered servo drive for position, velocity, and torque control of AC brushless and DC brush motors. It can operate on a distributed control network, as a stand-alone indexing drive, or with external motion controllers. Standard feedback is digital quad A/B encoder and two option versions are available to support brushless resolver (-R), or analog sin/cos encoders (-S).

Indexing mode enables simplified operation with PLC’s which use outputs to select and launch indexes and inputs to read back drive status. Additionally, a PLC can send ASCII data that can change motion profiles so that one index can perform various motions as machine requirements change.

The CANopen distributed control architecture is also supported. As a CAN node operating under the CANopen protocol, it supports Profile Position, Profile Velocity, Profile Torque, Interpolated Position, and Homing. Up to 127 drives can operate on a single CAN bus and groups of drives can be linked via the CAN so that they execute motion profiles together.

Operation with external motion controllers is possible in torque (current), velocity, and position modes. Input command signals can be ±10V (torque, velocity, position), PWM/Polarity (torque, velocity), or stepper format (CU/CD or Step/Direction).
