Product Description:
The S61401-SE is a digital servo drive produced by Kollmorgen as part of the S600 Servo Drives series. Designed for cabinet installation, the unit supplies regulated three-phase power to matched synchronous or induction servo motors so motion axes can be positioned quickly and repeatably in automated machinery. It interfaces with higher-level motion control through a SERCOS expansion board equipped with F-SMA fiber connectors, allowing the drive to fit into coordinated servo systems that require reliable fiber-optic communication.
Under continuous operating conditions, the drive delivers 14 A rms of output current, a level suited to medium-frame motors commonly used in packaging and material-handling equipment. Its power stage accepts line voltages from 230 to 480 V, allowing the same model to operate on lower- or higher-voltage mains systems without tap changes. For two-second transients such as acceleration spikes, the current can rise to 28 A rms, providing additional torque while the internal control loops remain stable. The enclosure carries an IP20 rating, so it must be mounted inside a control panel where access to live parts is limited. Total apparent power drawn at full load is 10 kVA, which is useful when sizing branch protection, conductors, and panel cooling.
Dynamic braking energy is dissipated by an internal resistor of 33 Ω, and the component can absorb up to 200 W before an external brake module is required. Input protection is provided by a 20 AT semiconductor-rated fuse, coordinated with the auxiliary 24 VDC logic supply that keeps the control electronics active during mains interruptions. Acoustic output at nominal switching frequency is 45 dB(A), which helps keep enclosure noise low during normal operation. The drive also supports load inductances from 2.5 mH to 15 mH to accommodate a wide motor range, and its compact dimensions of 100 mm width, 265 mm depth, and 275 mm height, together with a mass of 5 kg, support dense control cabinet layouts.
