Product Description:

The 800-2090 drive is manufactured by Copley Controls and belongs to the Accelnet CANopen Modules series. Designed as a networked servo and stepper amplifier, it converts CANopen commands into phase-accurate current for brushless, voice-coil, or stepper motors. In an automation cell, it forms the link between a central motion controller and individual axes while handling power delivery, feedback monitoring, and fault response. It is suited to distributed motion systems where network communication and compact installation are important.

Two auxiliary 5 V rails supply up to 500 mA each for encoders or sensors. A pair of differential analog inputs accepts ±10 Vdc commands and digitizes them at a 12-bit resolution, allowing fine torque or velocity references. Inside the torque generator, the current loop is processed every 16 kHz, which helps maintain stable motor control even with demanding dynamic loads. Machine states are captured through 18 opto-isolated digital inputs that can monitor limit switches, homing signals, or emergency-stop requests without external logic. Thermal protection is supervised by an internal sensor that trips the drive at 70 °C and removes gate signals to protect the power stage during sustained overload.

Stepper pulse streams are accepted up to 2 MHz, allowing external indexers to send high microstep rates. A certified STO circuit opens the power devices within 2 ms for rapid risk reduction when safe torque removal is required. In the cascaded regulator, speed and position calculations run at 4 kHz, complementing the faster torque loop and improving overall axis response. The power stage tolerates motor phases with as little as 200 µH of inductance and can energize a holding brake at 1 Adc. Seven programmable digital outputs and a solid-state relay rated at 300 mAdc provide status signaling or control an external contactor.
