Product Description:
The PRD-KD30030Z-50 is a digital servo amplifier produced by Kollmorgen for the Servostar CD Drives series. It functions as a closed-loop drive that conditions power, processes feedback, and issues torque or velocity commands to brushless servomotors in automated machinery. Signal conversion, loop control, and onboard diagnostics are combined in one chassis, simplifying axis integration within packaging lines, pick-and-place stations, and other motion-control equipment. The amplifier continuously compares command signals with motor feedback and adjusts its output to correct deviations during operation.
The drive accepts an analog command range of ±10 VDC, which the converter samples with an input resolution of 12 bits. Internal arithmetic runs at a controller clock frequency of 40 MHz, providing the processing speed required for synchronized control calculations. Current regulation is updated at 16 kHz, allowing the amplifier to respond to rapid load changes without excessive ripple. The velocity loop refreshes at 4 kHz, helping speed commands track their setpoints across the motor’s continuous operating range. The analog input window spans ±22,500 counts, allowing the host controller to map a wide process variable into the available torque range. An ±10 V analog output generated by an 8-bit digital-to-analog converter supports external meters or cascaded control loops. Zero-offset sampling occurs every 32 ms to reduce drift, and the default operating mode enables direct torque control when the unit powers up.
Position feedback is provided by a resolver, which supplies absolute shaft-angle data during startup and throughout normal operation. Peak torque events can be sustained at a 3:1 current ratio for 0.5 seconds, after which the foldback function reduces the output to continuous operating limits. The RS-232 maintenance port communicates at 115,200 bps using an 8N1 frame format. Momentary faults remain latched on the seven-segment display for 500 ms, allowing transient codes to remain visible after the triggering condition has cleared. The analog monitor output can display selected operating signals, including current or velocity behavior, during overload analysis. This monitoring capability helps isolate intermittent motion problems without interrupting the primary feedback and command paths.
