Product Description:

The CR10561 is a digital servo amplifier manufactured by Kollmorgen for the CD Servostar CD Drives series. As a closed-loop motion component, the unit regulates motor torque and velocity in automated machinery, linking the power stage of a system to its higher-level controller for coordinated axis movement. It belongs to the Compact Drive product family and is intended for applications that must maintain consistent position and speed accuracy while operating from a three-phase mains supply in industrial environments. Its role is to convert incoming electrical power and motion commands into controlled motor output for repeatable machine cycles.

Dynamic control is achieved through a current loop that refreshes every 62.5 µs, while the position loop is recalculated at 500 µs; both intervals support tight following error limits during rapid moves. Motor switching is handled by a PWM carrier of 8 kHz, and the drive can track commutation signals up to 400 Hz without losing synchronization. The drive is rated for continuous operation at 10 A, and it accepts a three-phase line with a frequency of 47 to 63 Hz. The short refresh intervals help the controller respond quickly during acceleration, deceleration, and steady-speed operation.

The power stage is fed by 230 VAC, while the control electronics draw a sink current of 1.5 A from an isolated logic supply held between 22 to 27 VDC. Protective circuitry trips if the DC bus rises to 430 VDC, and it also disconnects below 90 VDC or when the heat sink reaches 80 °C to prevent component failure. Command and diagnostic data move over the SERCOS interface, and motor feedback is processed through a resolver to maintain stable position information in noise-prone conditions. This feedback method is useful in equipment where electrical interference can affect signal quality during multi-axis operation.
