R911277120 (MHD112D-024-NP2-AN)

Why does the MHD112D-024-NP2-AN use relative position detection, and what are the commissioning implications?

The relative detection minimizes encoder complexity and enables rapid velocity/position updates, however an index/homing routine is required at startup to establish absolute machine coordinates. Its motion controllers must execute a reference move after power-up to guarantee repeatable datum.

How is the 32.0 Nm holding brake specified for the MHD112D-024-NP2-AN typically applied?

The spring-applied brake secures vertical or overhung loads during power loss or E-stop for preventing back-drive. It is recommended to size against reflected load torque plus safety factors, while use dynamic braking only for holding, not repetitive stop duty.

What mounting considerations follow from the 192 mm flange and 130 mm centering diameter?

These B5-style dimensions locate the motor concentrically to limit runout at the keyed shaft and reducing coupling wear. It is important to verify pilot fit tolerances and face flatness per the MHD project-planning manual to control shaft misalignment.

How does the keyed-shaft design of MHD112D-024-NP2-AN impact torsional integrity and coupling selection?

The key resists slip under transient torque peaks for easing alignment with pulleys or rigid couplings. For precision backlash control, pair with clamp-style or shrink-disc hubs and verify keyseat stresses against peak acceleration torque.

How should the side-A power connector orientation on MHD112D-024-NP2-AN be routed to minimize EMC issues?

It routes the motor power cable separately from feedback wiring to maintain shield continuity 360° at gland entries and ground the housing per Rexroth guidelines. It is important to keep parallel runs short and use star-point grounding at the drive.
