Product Description:

The MMC-SD-1.3-460 drive is produced by Kollmorgen and belongs to the MMC Standalone Smart Drives series. This self-contained unit combines power electronics with embedded motion sequencing so it can command a single servo axis directly from plant-level I/O. In automated packaging, material-handling, or light machine-tool setups, the drive supplies regulated three-phase current to a matched motor while supervising velocity, position, and fault conditions.

On a 460 VAC bus, the drive delivers up to 1.3 kW of mechanical output. Its continuous phase current is 3.0 A, while transient events can be supplied with a peak current of 6.0 A. To support that load, the input section draws a nominal power of 1.94 kVA at a line current of 2.44 A RMS. Current loops are refreshed every 125 µs and velocity commands every 250 µs, enabling tight torque and speed control for dynamic indexing tasks. Phase switching is synchronized to the internal PWM carrier, leaving minimal torque ripple, and these control cycles sit well below typical mechanical time constants so commanded force reaches the load almost immediately.

Control electronics are fed from a 24 VDC auxiliary rail that consumes 17 W under normal operation and draws 700 mA; the initial surge reaches 4 A for 10 ms. At mains energization, the power stage experiences a maximum inrush of 4.56 A RMS. The DC link stores energy in a 110 µF capacitor bank, limiting bus sag during regenerative deceleration. Resolver or encoder signals are accepted through a 150 Ω termination network, and the interface supports feedback frequencies up to 720 kHz for high-speed commutation. Overall thermal dissipation is 34 W, and the aluminum chassis weighs 10 lb, permitting easy panel installation.
