Product Description:
The S20630-SDS is a compact digital servo drive manufactured by Kollmorgen for the S200 Servo Drives series. It manages brushless motor phases from a low-voltage DC bus and supplies closed-loop torque, velocity, and position control to axes found in packaging, electronics assembly, and material-handling equipment. By integrating fieldbus connectivity and signal conditioning inside a slim housing, the unit forms the primary power interface between higher-level motion controllers and the mechanical load in decentralized automation panels.
With a 75 VDC supply, the drive outputs 500 W continuously and can reach 1500 W for up to 3.0 seconds during the minimum peak window. Its power stage supplies 6 ARMS of continuous phase current and tolerates 18 ARMS during rapid acceleration. Protection circuitry trips at 91 VDC bus overvoltage and at 17 VDC undervoltage to safeguard internal components. The output bridge supports motor inductances from 0.2 mH to 15 mH, allowing both low-impedance and high-inductance windings. Dynamic performance is enhanced by a fast current loop, and velocity refinement becomes available after a SynqNet option card establishes coordinated multi-axis control.
The current regulator runs at 5 kHz, while the velocity loop is capped at 800 Hz, giving tight response without exciting mechanical resonances. A carrier frequency of 31.2 kHz keeps output ripple above the audible range. Feedback is accepted through SFD/Hall channels as standard; EnDat 2.1 or sine encoders can be connected when the SynqNet option card with Micro-D plugs is installed, and a CAN card supports SFD/Comcoder devices. The base build has no electrical option because all I/O resides on modular cards. Cabinet space is minimized with dimensions of 152.4 mm height, 48.3 mm width, and 100.8 mm depth, and all functions operate from a nominal 90 VDC bus that remains below the overvoltage threshold.
