Frequently Asked Questions

Why would an engineer select a plain, sealed shaft on MHD112C-035-PG0-AN instead of a keyed or taper variant for coupling?

The plain shaft with a shaft seal supports backlash-controlled clamp couplings and protects lubricant paths. It reduces fretting from keyways and limits ingress in washdown or mist-laden environments.

How do the 130 mm centering diameter and 192 mm square flange on MHD112C-035-PG0-AN simplify retrofit into legacy Indramat MHD frames?

The DIN-style pilot and flange geometry standardize alignment and bolt pattern for minimizing adapter plates. Its reusing of existing gearheads or belt stages becomes feasible while maintaining concentricity and bearing preload assumptions.

What commissioning considerations follow from the power connector oriented to side A on the MHD112C-035-PG0-AN?

Its routing and bend radius must clear moving members on that side and phase sequence should be verified for correct rotation. Its shield termination should occur at the motor plate to minimize EMI.

How does motor length “C” in the MHD112C coding influence rotor inertia and tuning behavior compared with shorter variants?

The longer active stack raises torque constant and inertia, damping high-frequency resonances. Its drive autotuning often requires lower observer gains for trading slightly slower response for smoother following error under load disturbances.

Which drive families interface cleanly with the MHD112C-035-PG0-AN feedback and power topology for commissioning speed?

The Rexroth IndraDrive C (HCS) controllers accept classic MHD motor families with digital feedback for easing parameterization. Its cable sets and EMC connection plates are standardized for streamlining wiring and shield termination in control cabinets.
