Product Description:
The S20660-SDS is produced by Kollmorgen and belongs to the S200 Servo Drives series of motion-control products. As a servo drive it regulates current and voltage delivered to brushless motors so that industrial axes can follow programmed speed or torque commands with minimal error. It accepts 120 / 240 VAC mains supplies and is aimed at multi-axis machines that use SynqNet networking for deterministic coordination.
The drive can deliver 2000 W @ 240 VAC 3-ph continuously and supplies up to 18 ARMS peak during accelerations. Input stages tolerate a line inrush of 240 A 0-p @ 240 VAC for a duration of 2.0 ms, while the control electronics draw only 10 W. Continuous motor current is limited to 6 ARMS and shaft power reaches 1500 W at 3000 rpm. Peak apparent output is 6000 VA, and line compatibility spans the full 120/240 VAC rating. SynqNet communication is handled by the installed option board that also routes EnDat 2.1, Sine encoder and SFD/Hall feedback through micro-D connectors; there is no electrical option card fitted beyond this network module. Physical width is 64.0 mm, so two units can mount side-by-side in a 128 mm cabinet space.
Energy created during rapid deceleration is absorbed by the internal resistor up to 20 J @ 340 VDC, protecting the dc bus without external hardware. Available apparent power for short bursts is 6000 VA @ 240 VAC 3-ph, and motor compatibility covers inductances from 75 mH down to 1.5 mH, allowing pairing with both high-torque and low-inertia servomotors. Feedback support includes SFD/Comcoder via a CAN option card, and every unit recognizes SFD/Hall signals by default. Functionality mode lists “SynqNet option card with micro-D connectors,” matching the specified SynqNet connector. The housing stands 175.01 mm tall, extends 166.37 mm deep, and the electrical option slot is unused, keeping overall power density high for compact automation panels.
