The R911277786 (MHD112D-024-NG0-BN) is an MHD series servo motor, featuring liquid cooling and a plain shaft with sealing to protect internal bearings and prevent oil leakage. This model has a digital servo feedback (HSF) encoder for relative position sensing, and the power connector is configured on side B of the housing. Key dimensions include a 526 mm length, 192 mm flange, 130 mm centering diameter, and 32 mm shaft diameter. It delivers a continuous standstill torque of 48.0 Nm. The motor is suitable for operation at ambient temperatures from 0 to 40°C and installation altitudes up to 1000 meters. The external housing provides IP65 protection and F-class insulation.

Frequently Asked Questions

What does the HSF digital servo feedback in the MHD112D-024-NG0-BN actually do in closed-loop motion control?

It provides serial, noise-resilient position and velocity data directly to the drive to enable tight loop gains and smooth interpolation. It supports relative position tracking and seamless pairing with Rexroth drives.

What integration advantages come from the 192-mm square flange and 130-mm centering diameter on MHD112D-024-NG0-BN during retrofit or swap-out?

The standardized 192-mm square flange with 130-mm pilot ensures concentricity and repeatable alignment for minimizing shimming during retrofit. It speeds mechanical interchangeability across MHD112 variants and simplifies jigging for precision axes during planned downtime.

How is the 48.0 Nm continuous torque at standstill typically applied in industry scenarios for axes driven by the MHD112D-024-NG0-BN?

The 48.0 Nm continuous standstill torque suits clamping axes on machining centers, web-tension stands in printing and infeed stations on packaging lines. It enables steady force at zero speed for precise setup, threading, or dosing operations.

Can MHD112D-024-NG0-BN be commissioned with IndraDrive controllers, and which feedback interface is used during setup?

Yes, the MHD112D-024-NG0-BN uses Rexroth’s HSF digital feedback interface recognized by IndraDrive control sections for enabling automatic motor parameter identification and encoder handshake for quick commissioning and safe-torque-off integration.

How does the side-B power connection orientation on MHD112D-024-NG0-BN affect cable management in cabinets or gantry designs?

The side-B power connection routes high-current leads away from feedback cabling and moving elements for improving EMC and service access. It also supports alternate connector orientations for easing cabinet routing and gantry clearance limitations.
