Part of the S200 Servo Drives series, it supports CANopen network interface and position node functionality. The drive measures 152.4 mm in height, 48.3 mm in width, and 100.8 mm in depth, with a weight of 0.5 kilograms.
Internal Product Review
The S20250-CNS is a Kollmorgen S200 servo drive with a CANopen network interface for streamlined motion integration. A 1.5 ARMS continuous and 4.5 ARMS peak current rating, along with 400 Hz velocity loop bandwidth, support stable and responsive axis control. A 0.8 µs loop update period stands out as a strong advantage for fast, precise motion applications.

Product Description:
The S20250-CNS servo drive is manufactured by Kollmorgen and belongs to the S200 Servo Drives series. Acting as a compact amplifier, it interfaces between a motion controller and a brushless servomotor, delivering commanded torque and returning feedback across the machine network. Through this role, it enables accurate, repeatable positioning tasks in packaging, electronics assembly, and general factory automation.
Its power stage supplies 1.5 ARMS continuously and tolerates up to 4.5 ARMS for short acceleration events. These limits affect motor sizing and peak axis loading. Single-phase input at 120 VAC is internally doubled, or the unit accepts 240 VAC single-phase, so cabinet wiring remains simple. Closed-loop performance is supported by a velocity loop bandwidth of 400 Hz, while the current loop refreshes every 0.8 µs for tight dynamic response. Quadrature position latching reaches 625 kHz, with differential signals accepted at ±200 mV, allowing high-resolution encoders without added line drivers. The drive operates in Position Node mode over the CANopen interface, and its digital output can source 50 mA for external relays or status lamps. SFD/Hall, EnDat 2.1, sine encoder, and SFD/Comcoder options expand feedback compatibility through plug-in cards, but the base model comes without an electrical option card.
Mechanically, the aluminum housing is 48.3 mm wide, 152.4 mm high, and 100.8 mm deep, so multiple units can mount edge-to-edge on DIN rail without using excess panel space. With a mass of only 0.5 kg, it adds little load to vertical cabinets. M4 or #8 screws secure the drive, and a 50 m maximum feedback cable length permits remote motor placement on large machines. The CANopen network connector is on the front panel, and the SynqNet option slot accepts EnDat or sine encoder cards.
