Product Description:

The MMC-SD-16.0-460 is a standalone smart drive produced by Kollmorgen within the MMC Standalone Smart Drives series. Acting as a servo amplifier, it converts three-phase mains power and an auxiliary 24 V supply into regulated motor currents so axes in packaging lines, pick-and-place robots, and conveyor systems can be positioned under program control. The unit integrates its own motion processor and high-speed feedback ports, eliminating the need for a separate controller while maintaining precise synchronization in industrial automation tasks.

For the 24 V control rail, the drive draws 1750 mA during normal operation, which equals 42 W of power for its electronics, and withstands a 4 A inrush for 10 ms at startup. From the mains, nominal input reaches 16.8 kVA at 21.1 A RMS, and feeders must use conductors of at least 1.5 mm² (16 AWG) secured to terminals tightened to 1.25 Nm. The power section provides a continuous mechanical output of 16.0 kW by delivering 25.8 A RMS to the motor, and it can supply up to 73.0 A for short-term acceleration. Encoder or resolver signals are accepted at rates up to 720 kHz, enabling high-speed spindle or linear motor control. During initial energization, the unit may draw 39.2 A RMS, so upstream protection must be sized accordingly.

Energy on the internal DC link is stored in 1230 µF of capacitance, and a shunt switch engages when the voltage rises above 780 VDC to protect the power devices. Under rated load, the converter dissipates 390 W as heat, requiring forced ventilation inside the cabinet. The enclosure has a mass of 35 lb, which must be considered when determining panel support and vibration resistance. Adequate mounting hardware should support the drive securely without obstructing the airflow needed to remove heat from the enclosure.
