This servo drive has a current rating of 14A rms, a peak output current of 28 Arms, and supports voltages from 230 to 480V. It features a rated installed load of 10 kVA with a dissipation at rated current of 160 W.
Internal Product Review
The S61401-560 is a Kollmorgen S600 servo drive with 230...480 V support and a 14 A rms current rating. A 28 Arms peak output current paired with a 10 kVA rated installed load gives the drive strong headroom for dynamic servo applications. Low 15 W quiescent dissipation adds efficiency during standby, making the S600 platform a strong choice for tightly managed motion systems.

Product Description:
The S61401-560 servo drive is manufactured by Kollmorgen within the S600 Servo Drives series. Intended for cabinet installation, the unit converts fixed-frequency mains power into regulated three-phase current for synchronous or induction motors, supporting precise torque and velocity control in automated material-handling, packaging, and assembly equipment. As a stand-alone amplifier, it receives analog commands from PLC hardware and completes the current loop locally. This arrangement reduces controller loading while maintaining a fast motor response during changes in speed or torque demand.
The power stage operates from an input range of 230 to 480 V and delivers a continuous output of 14 A rms. Brief overloads can reach 28 A rms to satisfy acceleration peaks. With an output-current form factor of 1.01, the waveform remains nearly sinusoidal, limiting harmonic heating in the motor. The ±10 V command port presents an impedance of 20 kΩ relative to analog ground, so connected source devices draw minimal current. Internal conduction losses introduce a residual voltage drop of 5 V, while the AS electrical option adds extended monitoring features. Thermal output at full load is 160 W, while quiescent operation requires only 15 W. The required facility supply capacity for one drive is 10 kVA.
The enclosure measures 100 mm wide, 265 mm deep, and 275 mm high inside a control panel. It weighs 5 kg, allowing manageable handling during panel mounting. The current regulators remain stable when the connected motor has a phase inductance between 2.5 mH and 15 mH, protecting the drive from excessive rates of current change. A common-mode limit of 10 V relative to protective earth helps protect encoder insulation and nearby electronics during high-frequency switching. Adequate cabinet clearance should be maintained around the enclosure so the heat produced under load can be removed effectively. Motor and supply conductors should also be routed to minimize coupling between power wiring and low-level analog command signals.
