Product Description:
The ADP-090-09-S servo amplifier is produced by Copley Controls in the Accelnet CANopen Modules series. It accepts power from a regulated DC link and operates as a node on a CANopen network, generating pulse-width-modulated power for rotary or linear motors in industrial automation. By translating motion profiles from a PLC into synchronized current commands, the module controls torque, velocity, and position on a single axis while requiring minimal cabinet space.
During continuous operation, the drive supplies 3 Adc to the load while drawing 3.3 Adc from the bus, supporting heat-limited duty cycles with active current feedback. Its electrical backbone is a 90 Vdc DC bus, and the transistors switch at a 15 kHz PWM frequency so that current updates remain synchronized with the switching cycle. With a continuous output of 0.27 kW, the amplifier can power small servomotors in pick-and-place heads or light conveyors. The module has 12 opto-isolated inputs that allow field sensors or limit switches to control motion, while three sinking outputs report status to external relays. Command throughput remains high because the step-and-direction interface accepts pulses at 2 MHz. The velocity and position registers refresh at 3 kHz to support smooth interpolation.
For short bursts, the module raises phase current to 9 Adc and output power to 0.79 kW, but it limits this peak to one second to protect the transistors and connected motor windings. The bus can momentarily supply 10 Adc during these events, and the control loop can accommodate 30 kHz PWM ripple without becoming unstable. A minimum motor inductance of 200 µH is required to keep current ripple within tolerance at full switching speed. A watchdog tracks motion at the register update rate to detect interruptions promptly. Deterministic CANopen messages can trigger a digital output to brake the axis when a configured limit is reached.
