PRD-AG50000E-06 Kollmorgen
Wake Industrial LLC is not an authorized distributor of this product.
The Kollmorgen PRD-AG50000E-06 is part of the CD Servostar CD Drives series and supports a continuous current of 6 Arms, with peak current ratings of 12 Arms for 2 seconds and 18 Arms for 500 milliseconds. This drive features resolver feedback, an external 24 VDC logic power supply, and is protected with overtemperature and overvoltage trips set at 80 °C and 430 VDC respectively. Additional specifications include a heat dissipation of 80 watts and a pulse width modulation frequency of 8 kHz.
Internal Product Review
The PRD-AG50000E-06 is a Kollmorgen CD Servostar CD drive with resolver feedback and external 24 VDC logic power. Continuous output of 6 Arms with 12 Arms peak current for 2 s supports stable servo control under varying load demand. An 8 kHz PWM frequency and 0.25 s softstart charge time make this drive a strong choice for responsive, well-managed motion systems.

Product Description:
The PRD-AG50000E-06 is a digital servo drive produced by Kollmorgen within the CD Servostar CD Drives series. It converts rectified bus voltage into a controlled three-phase output that powers brushless and synchronous motors in automated machinery. Resolver feedback is processed inside the drive, so position, speed, and torque are regulated without external electronics. Typical duties include indexing axes, web tension control, and coordinated motion stages on assembly and packaging lines. The unit is installed in 208–480 VAC control cabinets and fastens to a heat sink plate, forming the link between the motion controller and the motor windings.
During continuous operation, the drive delivers 6 Arms to the motor, providing the thermal baseline for sizing conductors and cooling. Short bursts can be supplied at 12 Arms for two seconds or 18 Arms for 500 milliseconds, giving extra torque for acceleration and shock loads. The current waveform is generated by a PWM inverter that switches at 8 kHz, while the effective ripple seen by the motor windings is filtered to a carrier frequency of 16 kHz to minimize audible noise. An external control rail of 24 VDC powers the logic circuits, so parameter memory and fault diagnostics remain active whenever the main bus is de-energized. A 15 A line fuse protects the input, and the soft-start network limits inrush by charging the DC link within 0.25 seconds. The maximum surge current is rated at 30 A.
Thermal management is based on a dissipation figure of 80 W, so enclosure airflow must remove that heat to keep semiconductor junctions below the 80 °C overtemperature threshold. At that threshold, an internal sensor disables the gate drive. The protective logic also trips if the DC bus voltage exceeds 430 VDC or drops below 90 VDC, protecting the power stage from supply anomalies. A dedicated relay contact rated at 1 A reports any active fault to upstream safety circuits. Resolver loss, overcurrent events, or line fuse interruption triggers the same contact, providing a single status point for the machine controller.
