Product Description:
The 513 is a single-axis DC servo amplifier manufactured by Copley Controls within the DC Servo Amplifiers series. Designed for industrial automation, the module conditions low-level command signals and delivers controlled armature current to brushed or brushless DC motors. By regulating current rather than voltage, it produces tight torque control that supports precise positioning, speed regulation, and load sharing in packaging lines, semiconductor tools, and general motion platforms.
Its linear output stage can sustain a continuous phase current of 13 A, providing stable torque delivery for motors with limited thermal capacity. During short periods of increased demand, the amplifier raises the current to a peak of 26 A, allowing axes to overcome inertia or friction without losing loop accuracy. The power section provides 2360 W of continuous electrical output, while transient output can reach 3600 W for two-second bursts. This additional power supports rapid acceleration of conveyors and indexing tables. Pulse-width modulation operates at 25 kHz, which helps reduce audible noise and current ripple while limiting motor heating and improving velocity smoothness. A current-monitor port scaled at 4 A/V allows real-time observation of load conditions, and the 20 kΩ reference input allows motion controllers to command the unit without supplying excessive current.
For shorter acceleration demands, the amplifier can deliver 4650 W of output power for 500 milliseconds, providing a brief energy reserve without exceeding its thermal limits. Protection logic turns off the output when the internal heat sink reaches 70 °C, protecting semiconductor devices from excessive temperatures. The amplifier also shuts down when the supply rises above 196 VDC, preventing regenerative overvoltage. An additional shutdown occurs when the supply falls below 22 VDC, helping prevent low-bus commutation faults. With a weight of 1.32 lb, the module adds minimal mass to cabinet installations. Its ±100 V tachometer input accommodates high-speed feedback generators, allowing the control-loop bandwidth to reach 2.5 kHz without input saturation.
