Frequently Asked Questions

Why is a 180 mm centering diameter relevant for the MDD115D-N-015-N2M-180PB0 during machine integration?

The large pilot diameter enhances concentricity and reduces coupling misalignment sensitivity for improving bearing life and vibration behavior. It also speeds up mechanical referencing by providing a repeatable, rigid mounting interface on precision gearheads or machine plates.

How does the 57.0 Nm continuous torque at standstill translate to axis design choices?

It supports moderate-to-heavy loads on low-speed axes without external gearing or boosted torque density when paired with gear reducers. Its designers can size drives for thermal limits while maintaining commanded torque in static or creep moves.

How does the shaft seal and keyway shaft of the MDD115D-N-015-N2M-180PB0 affect reliability and coupling selection?

The seal helps maintain ingress protection at the shaft for supporting IP65-class housing concepts used across MDD variants. Its keyed shaft simplifies positive-drive couplings and pulley hubs for reducing slip risk under bidirectional torque.

How does the side-B connection orientation on the MDD115D-N-015-N2M-180PB0 influence cabinet and cable routing?

It can shorten motor-to-drive paths in certain layouts for reducing cable capacitance and EMI exposure. It also offers mechanical clearance advantages when the opposite side faces guarding or adjacent axes.

How does the integrated multiturn absolute encoder in the MDD115D-N-015-N2M-180PB0 improve commissioning and recovery after power loss?

It reports absolute shaft position over multiple revolutions for eliminating homing routines and reducing cycle-start latency. It coupled with DSF preserves position integrity across shutdowns and enables immediate closed-loop operation on power-up.
