Product Description:
The ACJ-055-09-S is a digital servo drive module produced by Copley Controls for the Accelnet CANopen Modules series. It delivers pulse-width-modulated power to brushless or brushed servomotors. The module exchanges motion commands over a CANopen network, allowing distributed velocity and position control in industrial automation cells. Its digital control architecture coordinates motor current with commands from the connected motion controller, supporting responsive operation during acceleration, steady movement, and positioning.
The drive can source a peak phase current of 9 Adc for rapid acceleration and maintain a continuous output of 3 Adc while the axis runs at steady state. Its thermal design supports a peak output power of 490 W and a continuous output power of 163 W without thermal derating. Current regulation is performed by a control loop operating at 15 kHz, so torque commands are updated every 66 microseconds to minimize lag between controller demand and motor response. The output resistance is 0.075 ohms, which reduces resistive losses at high currents. For system protection, the high-voltage DC bus must remain between 14 Vdc and 56 Vdc; the amplifier inhibits switching when the voltage crosses either trip point. A minimum load inductance of 200 microhenries is required to limit ripple current, and the PWM transistors switch at 30 kHz to keep carrier noise above the audible range.
The velocity and position loops update at 3 kHz, coordinating the outer motion loops with the faster inner current loop for smooth motion profiles. Encoder feedback supports a maximum input frequency of 230 kHz, allowing the drive to process rapid signal transitions from high-resolution feedback devices. An analog sine-cosine incremental encoder signal is interpolated at 10 bits per cycle to increase the available position resolution. The onboard encoder supply provides 5 Vdc at up to 400 mA, eliminating the need for a separate feedback power regulator. Undervoltage and overvoltage monitoring protect the switching stage, while the required motor inductance helps maintain stable commutation and control current ripple during operation.
