Product Description:
The SE2302-5 is a DC motor controller produced by Kollmorgen within the SE2000 DC Motor Controllers series. Designed for closed-loop armature or tachometer feedback systems, the unit modulates DC voltage to control the speed of permanent-magnet or shunt-wound motors used in conveyors, winding stations, and automated tooling. By integrating signal conditioning and overload protection, the controller acts as the command element between a single-phase AC supply and the rotating load in an industrial automation cell.
Running from a single-phase 115 or 230 VAC line, the controller accepts sources that vary within a ±10 % window, and it tracks line cycles at 50/60 Hz ±2 Hz without loss of synchronization. On a 115 VAC feeder the armature section delivers 0-90 VDC, while speed is held within ±2 % at a 95 % load change. Field excitation for the same input range is 50/100 VDC, allowing separate-wound fields to match motor nameplates. For intermittent surges such as start-up inertia, the power stage endures 150 % for 1 min above its continuous rating, and continuous duty operation is supported once thermal equilibrium is reached.
With a 230 VAC source the armature channel extends to 0-180 VDC, and the field terminals supply 100/200 VDC to accommodate higher-voltage machines. When a tachometer is connected, closed-loop correction tightens speed error to ±0.5 % at a 95 % load change, giving precise process control up to the ambient limit of 55 °C. Fault management is handled by inverse-time over-current, field-loss, and tach-loss algorithms; any trip energizes a Form C relay that is wired to terminal block 7 as 1 N.O., 2 COM, 3 N.C. for easy interface with external alarms. These safeguards, combined with continuous monitoring, maintain uptime while the controller operates within the overload and regulation margins already described.
