Product Description:

The S20260-CNS is a servo drive manufactured by Kollmorgen as part of the S200 Servo Drives series. This compact module regulates torque, velocity, or position for brushless servomotors used in industrial automation cells, packaging machinery, and electronic assembly lines. By accepting low-voltage control commands and modulating the power supplied to a connected motor, the drive forms the actuation layer between a motion controller and the mechanical load. Its compact format helps it fit cabinet installations where precise axis control is required without a large drive footprint.

The drive operates from 120/240 VAC single-phase or three-phase mains, which the internal rectifier converts to a DC bus level of 320 VDC for high-bandwidth current loops. Under sustained duty, the power stage delivers 1.5 ARMS continuous output, yet it can provide up to 4.5 ARMS peak during rapid acceleration to handle dynamic loads. The IGBTs are pulse-width modulated at 20 kHz, so current ripple is reduced and audible noise is pushed above the normal hearing range. A CANopen Position-Node control set coordinates motion profiles, while SynqNet and CAN option cards add encoder channels for SFD, Comcoder, and EnDat feedback devices. This arrangement supports several feedback formats without requiring a different base drive for each motor style.

During power-up, an inrush limiter protects the DC bus; the surge tops at 140 A for roughly 1.5 ms, minimizing stress on upstream breakers. Motor matching is supported over an inductance span from 5 mH to 300 mH, permitting use with low-reactance frameless motors as well as higher-inductance framed models. The housing is 175 mm tall, 54.8 mm wide, and 131.6 mm deep, so it fits standard control cabinets while keeping wiring access straightforward. Its mass is 0.84 kg, which helps when multiple axes are mounted on the same back panel. Communication and feedback options support multi-axis systems that require coordinated servo response.
