Product Description:

The M4410-22120A is a digital DC motor controller produced by Kollmorgen within the M4000 Digital DC Drives series. Designed for panel mounting inside industrial cabinets, the unit rectifies three-phase supply power and modulates the resulting DC so that connected motors can accelerate, decelerate, or hold steady speed under closed-loop supervision. By manipulating current rather than frequency, the drive offers stable torque at low speeds, making it suitable for material-handling lines, unwind stations, and other machinery that relies on precise DC motor regulation.

The power section supplies an armature voltage that spans 0 to 500 VDC, enabling full-range control over standard 240 or 500-volt motors. A dedicated field output of 300 VDC energizes the motor field winding so that flux remains constant while speed varies. The drive is rated for 10 HP, which is the maximum mechanical output it can deliver under continuous duty. Incoming power must be 460 VAC three-phase power within a line-frequency window of 48 to 62 Hz. Because the design is non-regenerative, energy created during braking is dissipated through the armature rather than returned to the mains, simplifying installation where line regeneration is not permitted.

The control layer provides 10 digital inputs, six Form C relay outputs, and an isolated RS-485 port for parameter download or remote diagnostics. Within its protected speed window of 50:1, the drive can sustain a momentary overload of 150% for 1 min without tripping, supporting short acceleration bursts. Mechanical packaging measures 30.0 in high, 20.0 in wide, and 9.0 in deep, allowing straightforward placement in NEMA enclosures. Forced ventilation paths are sized so that the non-regenerative topology and six-relay interface remain thermally stable even when all control inputs are active.
