Keep the reflected load inertia near the rotor inertia to maintain control bandwidth; with small-torque servos, belt ratios often provide the needed reduction. The resolver’s absolute capability helps recovery from stops, but poor inertia match will still limit dynamic response.

A DIN-6885 keyway shaft favors keyed hubs or pulleys; use interference class and key fit to handle peak torque without fretting. Balance the coupling and pulley to G 2.5 or better for high-speed service to avoid synchronous vibration.

MDD motors use separate power and 12-pin feedback connectors, with the PTC temperature sensor routed via the power connector harness. Follow the crimp/solder guidance for the power plug and ensure feedback cabling and gasket integrity when re-tightening.

Its high base speed with modest continuous torque suits small pick-and-place, electronics handling, and light packaging axes needing quick indexing rather than heavy cutting loads. The resolver-absolute feedback and pilot/keyed-shaft geometry simplify precise, repeatable, and rugged integration.

On vertical or safety-critical axes, specify a mechanical brake on the load or a gearbox brake to hold position when the drive is disabled. The drive can control a brake circuit natively when a brake is present, but this variant requires external holding.
