Copley Controls Corporation Model 5121 CE Brushless Servo Amplifier These are USED Model 5121 Servo Amplifiers that are in good working order. No testing was performed. No manuals, cords/cables, or additional items are included if not listed or shown. The 5xx1 models are third-generation amplifiers for Hall commutated dc brushless motors. Operating from +24 to +225 VDC transformerisolated unregulated power supplies, models output peak currents from ±10 to ±30A, and continuous currents of ±5 to ±15A. Built with surface-mount technology, these amplifiers offer a full complement of features for DC brushless motor control. Torquemode operation is standard, and there are three choices for velocityloop operation. Brush tachometers can be used with the standard amplifier. Brushless tachometers are supported with the “U” option. Frequency to voltage conversion of Hall or encoder signals gives tachless velocity-loop operation with the “V” option. Torque mode is used typically with digital controllers that calculate position and velocity from the motors encoder. Velocity loops using brush or brushless tachometers give the best low-speed control. Hall tach operation works well for high speed applications such as spindles. Encoder tach velocity loops give a wide speed range and lower ripple near zero velocity. Separate current-limits provide protection for motors while optimizing acceleration characteristics. Peak current, continuous current, and peak-time are individually settable. We have 3 of these onhand. The successful bidder will have an opportunity to purchase another one or two at the same price. Buy all three and get a 10% discount!
