Product Description:
The CR06261 is a compact digital servo drive manufactured by Kollmorgen within the CD Servostar CD Drives series. As part of the Compact Drive product family, it conditions motor phase currents and executes position, velocity, and current loops for brushless servomotors installed in pick-and-place heads, feeders, or conveyor axes. By translating fiber-optic SERCOS commands into regulated torque, the unit links machine controllers to motion hardware and maintains precise synchronization across automated production lines.
The analog reference channel is sampled at 14-bit resolution, enabling fine adjustment of torque demand. Motion commands enter through the SERCOS interface, and the drive refreshes commutation vectors at 16 kHz, so magnetic alignment remains stable even at high speed. Continuous phase current is supported up to 6 Arms per phase, while auxiliary digital outputs can source 60 mA, which is enough to drive status LEDs or small relays. The logic section operates from an external 24 VDC supply, isolating the control electronics from the motor bus. Communication packets are exchanged every 2 ms, providing deterministic control of multiple axes.
Position feedback is managed by a resolver with an accuracy of 19 arc-minutes. The excitation winding receives 4.25 VAC, and the secondary produces 2 VAC while drawing no more than 55 mA ACRMS. Resolver operation remains linear when its resistance stays below 120 Ω. The position loop closes at 2 kHz, while the velocity loop updates at 4 kHz. A fault relay rated at 1 A at 24 VDC can disconnect power or notify a safety PLC when operating limits are exceeded. The separate 24 VDC logic supply keeps the control voltage independent of the drive bus, helping isolate low-voltage control circuits from the motor power section.
