Product Description:

The M4407-100200 is a digital DC drive manufactured by Kollmorgen as part of the M4000 Digital DC Drives series. It regulates armature current and field excitation for DC shunt motors used in conveyors, winders, and other speed-controlled processes. By converting a three-phase AC supply into a controlled DC output, the unit lets a motion controller command torque or velocity directly at the motor terminals, streamlining closed-loop automation schemes.

The drive accepts a nominal line voltage of 460 VAC, and it is wired for three-phase mains, so phase rotation must be verified during installation. Under full load, the rectifier section draws 11.3 A from the AC supply, while the power stage can deliver 13.5 A of regulated armature current. The armature output is limited to 500 VDC, allowing high-speed operation without field saturation. No factory-installed AC line protection is included, so external fusing is required. The chassis carries no blower starter and no additional options, which keeps panel layout simple, and AC line conductors, field leads, and control wiring terminate on the base plate because no separate chassis option is fitted.

Motor sizing for this module reaches 7.5 HP at the shaft when paired with a Kollmorgen or equivalent DC shunt machine. A dedicated field regulator supplies 300 VDC and supports field weakening, so speed can rise above base speed without exceeding the motor's mechanical speed limits. Dynamic braking energy is handled through a single brake resistor rated at 24 Ω / 300 W, and enclosure airflow must be verified because a blower starter is not provided. The drive uses a Regen Drive Module configuration, returning excess energy to the supply instead of dissipating it as heat. Motor compatibility is limited to DC shunt designs, and the MD21 configuration flag is assigned to this unit.
