Product Description:
The 7229AC is a servo drive module produced by Copley Controls for the DC Servo Amplifiers series. It converts single-phase mains power into controlled current for closed-loop motion systems. In industrial automation, the unit operates between a motion controller and an AC brushless motor, modulating current so torque, speed, and position follow real-time commands in assembly equipment, packaging lines, and robotic systems.
Continuous output capacity reaches ±10 A, which is the symmetrical current the amplifier can deliver continuously without thermal derating. For short acceleration periods, it supplies a peak current of ±20 A, allowing additional torque during rapid indexing. The input section accepts a mains range of 32–132 VAC at a nominal frequency of 50/60 Hz, allowing operation with several common industrial power sources. The single-phase power input requires line and neutral conductors, simplifying cabinet wiring. With an output rating of 1.5 hp, the module can support midsize rotary axes used for pick-and-place heads or feed rollers. Internal circuitry monitors the DC bus and activates overvoltage crowbar protection when incoming voltage spikes exceed safe limits. A dedicated shutdown loop responds to phase-to-phase and phase-to-ground faults, providing short-circuit protection for the drive and connected equipment.
The 7229AC is intended for AC brushless servomotors, so its current-loop bandwidth and commutation algorithms are suited to motors with sinusoidal back electromotive force. Front-panel LED indicators display power enablement, drive status, and fault codes, providing immediate diagnostic information without separate instruments. The aluminum housing measures 7.50 × 7.00 × 2.72 inches, allowing side-by-side installation on a standard subpanel while preserving clearance for airflow across the heat sinks.
