Copley Controls ARM98AC-N25 – Single Axis Servo Drive | Accelnet Panel Series
Engineering Background
Copley Controls is a recognized leader in high-performance digital servo drives, widely deployed across semiconductor equipment, medical robotics, aerospace test rigs, and precision industrial automation. The Accelnet Panel (ARM) series represents the company’s compact, panel-mount servo amplifier platform engineered for demanding single-axis motion control applications requiring tight velocity and position loop performance.
Product Positioning
The ARM98AC-N25 (P/N 1080-01385 / 800-1843 / 907.00.67) is a single-axis digital servo drive designed to deliver precise torque, velocity, and position control for brushless AC servo motors. It is the preferred choice for procurement engineers sourcing a compact, DIN-rail or panel-mountable amplifier with CANopen or RS-232 commissioning capability and robust short-circuit protection.

Engineering Advantages
- High current density: 25 A continuous / 50 A peak in a compact panel-mount footprint reduces cabinet space requirements.
- Multi-mode control: Seamless switching between torque, velocity, and position modes via CME2 software or CANopen objects.
- Universal feedback: Supports incremental encoder, resolver, and Hall-effect sensors without additional interface cards.
- Robust protection suite: Hardware and firmware over-current, over-voltage, and thermal shutdown protect both drive and motor investment.
- CANopen DS-402 compliance: Plug-and-play integration with Beckhoff, Siemens, B&R, and other CANopen master PLCs.
- CME2 commissioning software: Graphical auto-tuning, scope, and fault diagnostics reduce commissioning time significantly.
System Architecture & Signal Flow
The ARM98AC-N25 accepts a command reference (analog ±10 V, PWM, or CANopen position/velocity/torque word) from the host controller. The internal DSP closes the current loop at 20 kHz, the velocity loop at ~4 kHz, and the position loop at ~2 kHz. Encoder feedback is processed in hardware for zero-latency commutation. The drive outputs a 3-phase PWM voltage to the motor windings, with regenerative energy managed via an internal or external shunt resistor. Fault status and drive state are reported back to the host via CANopen PDOs or RS-232 ASCII protocol.

Technical FAQ
Q: Is the ARM98AC-N25 compatible with Beckhoff TwinCAT via CANopen?
A: Yes. The drive is CANopen DS-402 compliant and can be configured as a CiA 402 slave device under TwinCAT NC/PTP or TwinCAT 3 motion control.
Q: What is the difference between ARM98AC-N25 and ARM98AC-N12?
A: The N-suffix denotes continuous output current rating. N25 = 25 A continuous; N12 = 12 A continuous. All other architecture and interface features are identical within the ARM98AC family.
Q: Can this drive operate from a 110 VAC single-phase supply?
A: The ARM series accepts a wide AC input range. Confirm the specific input voltage range on the unit nameplate or contact us for the datasheet applicable to your revision.
Q: Do you provide the CME2 setup software and cable?
A: CME2 software is freely available from Copley Controls. RS-232 programming cables can be supplied upon request. Contact us when placing your order.
Q: What warranty is provided?
A: We offer a 90-day functional warranty on all tested units. Extended warranty and repair services are available — please inquire.
