The Kollmorgen S22460-SRS is an S200 Servo Drive with a continuous power rating of 8000 W for three-phase operation and a nominal DC bus voltage of 320 VDC. Part of the S200 Servo Drives series, it has a current rating of 24 ARMS continuous and 48 ARMS peak, and supports feedback types such as SFD/Halls on all units. The drive includes SynqNet option card functionality with standard RJ-45 connectors and operates at a ripple frequency of 16 kHz.
Internal Product Review
The S22460-SRS is a Kollmorgen S200 servo drive that stands out for 8000 W continuous 3-phase power and 24 ARMS continuous current. SynqNet option card support with standard RJ connectors pairs well with the RJ-45 interface for straightforward network integration. Stable drive behavior and 60 J bus energy absorption make the unit a very capable choice for demanding servo applications.

Product Description:
Kollmorgen manufactures the S22460-SRS as part of the S200 Servo Drives series, and the internal product type code also classifies it as an S200 servo drive. This three-phase unit regulates current and velocity for brushless servo motors in automated machinery, coordinating motion through a SynqNet network. By converting line voltage to a controlled DC bus and modulating phase outputs, it supplies precise torque so that axes follow programmed trajectories with repeatable precision. No additional electrical option boards are required for standard operation, yet modular cards are available, including EnDat 2.1, sine encoder, and SFD/Comcoder interfaces that connect through SynqNet; factory support for SFD/Hall sensors is present, and the functionality mode supplied in this unit uses standard RJ-45 ports for cabling.
On the power side, the S22460-SRS delivers 8000 W of continuous three-phase output when supplied from a 120/240 VAC mains source. Its internal rectifier maintains a nominal DC bus of 320 VDC, and the overvoltage trip activates at 407 VDC to protect the power stage. Continuous phase current is 24 ARMS, while the drive supports 48 ARMS peak to handle acceleration demands, and the matching line current is 24 ARMS under full load. Motor compatibility covers inductances from 0.6 mH to 30 mH, allowing use with low-reactance or high-torque windings. Shaft power reaches 5000 W at 3000 rpm, linking electrical output to mechanical performance. The control electronics draw 10 W in steady state and accept a 10 A zero-peak inrush current.
Protection logic disables the inverter if the DC bus falls below 150 VDC or if regenerated energy exceeds 60 J, making external shunts necessary for high-inertia axes. A carrier ripple of 16 kHz keeps current loops responsive while minimizing audible noise. The peak-current window lasts 3.0 s, after which the controller returns to its continuous rating.
