Product Description:
The 5211CE is a DC servo amplifier manufactured by Copley Controls for the DC Servo Amplifiers series. It conditions analog or PWM reference commands and delivers bidirectional current to permanent-magnet motors, enabling precise positioning and speed control in pick-and-place machines, small gantries, and semiconductor handlers. By integrating fault reporting, current feedback, and signal conditioning, the module serves as an intermediate power stage that links low-voltage motion controllers to higher-voltage motor windings in industrial automation cells.
The control loop has a bandwidth of 3 kHz, so velocity or torque errors are corrected rapidly. The amplifier supports a continuous motor output of ±5 A at ±173 V. Its output stage has a resistance of only 0.4 ohm, which minimizes resistive power losses. Pulse-width modulation occurs at 25 kHz, placing switching noise above the audible range and reducing torque ripple in low-inductance windings. For rapid acceleration or short overloads, the amplifier can deliver ±10 A at ±171 V, after which thermal foldback protects the power devices. A differential gain of X1 is applied to the reference input, allowing the commanded voltage to translate directly into output current without additional scaling.
Connector J1 is rated for 30 A, providing ample margin above the peak current rating. Reference commands of up to ±20 V are accepted through a high-impedance path of 94 kilohms, so upstream digital-to-analog converters are only lightly loaded. Logic inputs transition at a 2.5 V threshold and have 10 kilohms of internal resistance. A +5 V fault line changes state after a 50 ms reset interval to indicate drive status. The amplifier weighs only 1.1 lb, permitting direct mounting on moving axes where cabinet space is limited or shorter cable runs are preferred.
