Frequently Asked Questions

How does the integrated multiturn absolute encoder in MDD115D-F-015-N2M-130GA0 aid commissioning and repeatability?

It preserves position across power cycles and supplies multi-revolution data for reducing homing routines and improving startup alignment. Its data pairs with digital servo feedback to deliver deterministic position/velocity reporting to Rexroth drives for accurate path control.

What advantages does Digital Servo Feedback (DSF) provide over resolver feedback in the MDD series?

The DSF communicates digitally with DDS/DKS controllers to enable parameter memory in the feedback unit and simplify pairing/diagnostics. Its resolver systems need analog decoding and different drive variants.

Why is the 130 mm centering diameter on MDD115D-F-015-N2M-130GA0 important for machine integration?

The large register ensures coaxial alignment to the machine interface to minimize runout and coupling stress. It supports consistent dynamic response when paired with a standard housing and D-length body in size-115 frames.

How do shaft choices (plain shaft with seal on MDD115D-F-015-N2M-130GA0) influence coupling and ingress protection?

It simplifies keyless coupling (clamp or bellows) and supports IP-rated sealing at the nose. It helps maintain lubrication integrity and reduces backlash sources compared with keyed interfaces.

How does the motor’s 57.0 Nm continuous torque at standstill influence axis selection for MDD115D-F-015-N2M-130GA0?

It lets designers size for holding/low-speed process forces that is useful on vertical Z-axes or unwinders, while maintaining thermal margins. Its 57 Nm aligns with applications needing sustained torque without a brake.
