Product Description:
The CB10550 is a digital servo drive manufactured by Kollmorgen and supplied through the CD Servostar CD Drives series. Belonging to the Compact Drive family, it converts a three-phase, regulated mains supply into precisely metered motor currents for automation tasks that demand tight torque and speed control. Integrated sine-encoder feedback lets the unit supervise instantaneous position, while its dual-loop architecture supports machines such as electronic component placers, indexing conveyors, and laboratory automation stages that must follow dynamic motion profiles with minimal lag.
The power stage accepts a nominal bus derived from a 230 VAC line voltage and delivers a continuous output of 10 A rms, with a short-term ceiling of 20 A rms for up to 2 seconds to overcome inertia during acceleration. Fast magnetic regulation stems from a current-loop bandwidth of 2.5 kHz and an update rate of 16 kHz, allowing small error signals to be corrected before they propagate into the velocity loop. The outer loop reaches 400 Hz and receives fresh data at a controller refresh rate of 4000 Hz, so commanded speed changes are executed quickly without excessive overshoot. Sine interpolation and resolver-to-digital conversion help maintain smooth torque when the motor operates near its upper mechanical limits.
Signal fidelity is supported by an analog resolution of 14 bits, which reduces quantization error in the control processor. On the encoder side, the drive tolerates base carrier frequencies up to 1.2 MHz. The sensor interface provides a stabilized 5 VDC supply, while the feedback signal has an amplitude of 1 V peak to peak for low-noise operation. Internal interpolation processes feedback tracks at a factor of 256, allowing fine position increments even when the external sine encoder has a maximum count rate of 125 kHz. The expanded count density supports precise velocity linearity, and the rapid update timing helps the control loops respond to small changes in commanded motion. Stable feedback processing also helps the drive maintain consistent torque production throughout its operating range.
