Product Description:

The S20360-VTS is a digital servo drive manufactured by Kollmorgen for the S200 Servo Drives series. In an automation cell, it interfaces between the motion controller and a brushless servo motor, converting the incoming AC supply into controlled current and voltage that generate precise speed or torque profiles. This arrangement lets the drive respond quickly to command changes and load variation during motion. It is intended for panel-mounted use in packaging, material handling, and electronics assembly lines because it combines power electronics, feedback processing, and safety functions in a single enclosure.

With a three-phase 240 VAC input, the drive can deliver up to 1100 W of continuous mechanical power to the motor while drawing only 5.0 ARMS from the mains. The current loop is rated at 3 ARMS continuous, 9 ARMS peak, and peak current is permitted for 3.0 s to handle acceleration. A startup surge of 140 A appears briefly as inrush current, yet the internal bus capacitors can absorb 15.5 J of regenerated energy without external braking resistors. Operation is supported from a supply range of 120/240 VAC. The drive can still support 500 W at 3000 rpm when the heat sink is at 40 °C, and velocity or torque mode is selected through drive parameters.

Control precision comes from a 3 kHz current-loop bandwidth that works with SFD/Hall feedback, a CAN SFD/Comcoder card, or sine and EnDat 2.1 encoders on SynqNet cards. The internal DC link runs at 320 VDC from the rectified input, and ripple on that link is limited by a switching frequency of 20 kHz. Motors from 2.5 mH to 150 mH inductance are supported, enabling a wide torque-speed envelope. Physical dimensions are 175.28 mm high, 54.75 mm wide, and 131.57 mm deep, which helps the unit fit compact control cabinets. Cooling is handled by natural convection.
