Product Details:

KOLLMORGEN CR06703-R is a compact digital servo amplifier from the classic ServoStar CD series, the suffix R stands for resolver feedback version, widely matched with AKM series servo motors for ENGEL injection molding machines, packaging machinery and automated handling equipment. It adopts advanced closed-loop control algorithm to achieve stable torque output and fast dynamic response, which is suitable for light and medium-load motion axes requiring high positioning accuracy and synchronous tracking. It is commonly used for ejection control, material feeding control and auxiliary adjustment units on plastic molding production lines.

This servo amplifier is specially optimized for resolver signal input, it can receive rotor position, speed and angle data from resolver-equipped servo motors to form a complete closed-loop motion control system. It uses independent power terminal and signal port layout to reduce electromagnetic interference generated by hydraulic pumps and switching solenoid coils. The internal power device has overcurrent and voltage suppression design, and the housing reaches IP20 protection grade, suitable for installation inside electrical control cabinet. The fast loop response supports rapid acceleration and deceleration of the motor, maintaining stable positioning precision during continuous cyclic operation.

Engineers can tune speed loop gain, position loop gain and feedforward parameters through Kollmorgen dedicated MotionLink software according to different process requirements. Built-in multiple detection circuits continuously monitor bus voltage, output current and internal temperature. If overheating, overload, overvoltage or resolver signal loss is detected, the servo amplifier will quickly cut off output and trigger alarm to prevent mechanical collision and motor burnout. The overall mechanical structure is reinforced for vibration resistance, suitable for long-time continuous production.

This KOLLMORGEN CR06703-R servo amplifier has been discontinued by the original manufacturer. It is available in the industrial automation aftermarket as a tested replacement spare part for legacy ENGEL injection molding equipment. Maintenance technicians can complete replacement safely after power cut, without modifying the original wiring layout and control scheme.

It is a popular ServoStar CD series resolver-type drive spare part among automation rebuilders, delivering stable and precise motion control performance for light and medium-duty auxiliary axes.
