Product Description:
Kollmorgen’s DC motor controller SE2222 belongs to the SE2000 DC Motor Controllers series. Designed for industrial automation panels, the unit follows a run-brake control scheme that lets a connected motor start, coast, or stop under preset logic, and it operates under a continuous duty cycle. An integrated dynamic-brake circuit dissipates regenerative energy, while the built-in motor contactor simplifies wiring. Within a motion cell or material-handling station, the controller regulates armature voltage so conveyor, winder, or pump drives can change speed on demand without software-heavy interfaces.
The enclosure is rated at NEMA 4/12, meaning dust, oil, and water splashes cannot reach internal electronics when the door is closed. Across its output, the controller maintains a speed range of 30:1, so a motor can be driven from low creep to rated rpm with the same torque profile. Closed-loop armature feedback keeps steady velocity within ±2% of the set point, compensating for load or line variations. For short overload conditions, the power stage tolerates 150% for 1 minute, giving conveyors or extruders a reserve for break-away torque. Operation is specified up to 1000 m elevation without derating, and upstream line protection is handled by an internal circuit breaker that disconnects faults faster than external fusing.
Cabinet placement should allow normal airflow and keep the enclosure within its operating limits. The controller handles ambient temperatures up to 40 °C, and performance remains stable in air with up to 95% non-condensing humidity, so it can be used in humid indoor areas as long as moisture does not collect on the terminals. Its rectangular housing measures 9.50 in wide, rises 13.00 in high, and projects 8.50 in deep, allowing direct wall mounting beside drives or contactors without exceeding typical panel depths. With proper clearance around the housing, forced ventilation is unnecessary during normal operation.
