S20660-SRS

S20660-SRS is a Kollmorgen unit in the S200 Servo Drives series. It supports 120/240 VAC operation at all current ratings. At a 240 VAC input, the nominal bus voltage is 320 VDC, while a bus overvoltage fault occurs at 407 VDC with a +5% tolerance to protect the drive from excessive bus voltage. The continuous current rating is 6 ARMS, and the peak rating is 18 ARMS for up to 3.0 seconds. With 240 VAC three-phase power, it supplies 2,000 W continuously and up to 6,000 VA at peak output.

The current loop updates every 0.8 µs for rapid motor-current regulation. Its maximum current-loop bandwidth is 3 kHz, while the recommended bandwidth is 2 kHz for normal tuning and control. SFD and Hall feedback are supported on all units. SFD/Comcoder feedback uses a CAN option card, while EnDat 2.1 and sine-encoder feedback use a SynqNet option card.

The network bus is SynqNet, and the functionality mode uses a SynqNet option card with standard RJ connectors. An RJ-45 network connector provides the physical network connection. There is no electrical option. The unit measures 175.01 mm in height, 64.0 mm in width, and 131.57 mm in depth.
