Product Description:

The PRD-P320260D-C2 is a servo drive manufactured by Kollmorgen within the SP Servostar Servo Drives series. This unit conditions three-phase mains power and regulated logic supplies to command PMAC-compatible synchronous motors used in industrial automation cells, handling torque, velocity, and position loops at the drive level. By accepting control words from a Delta Tau PMAC2 controller, the product links motion sequences created in the PLC to the mechanical axis.

The power section draws balanced 400 VAC lines through a three-phase rectifier and can absorb up to 8.68 kVA during rated operation. Continuous armature current is electronically limited to 20 A RMS per phase, providing current-feedback scaling of 7.07 A/V while delivering a sustained mechanical output of 7.3 kW. Torque commands presented as a ±10 V signal are converted to current using the factory analog input scaling of 5.66 A/V. The analog circuitry is energized by a bipolar ±15 VDC rail generated internally. Control electronics that process serial-digital U/V current feedback operate on a dedicated 8 VDC logic bus, isolating the low-level processors from the power stage. Overvoltage protection activates at 430 VDC, and the overcurrent channel permits 40 A RMS per phase for two seconds to handle acceleration peaks.

An external 24 VDC source powers the I/O, fieldbus transceivers, and Mini-D 36-pin PMAC connector. This separate source allows the drive to exchange status information with the Delta Tau PMAC2 even when mains power is removed. During normal operation, switching losses and auxiliary circuits dissipate 240 W through the heat sink, so cabinet airflow must remove the generated heat. Adequate airflow prevents the inverter from reaching its thermal shutdown threshold of 118 °C during operation in mid-power packaging lines, indexing tables, and material-handling axes.
