Frequently Asked Questions

How does the liquid-cooled housing of the MHD112D-024-NG2-BN improve duty capability under cyclic loads?

The liquid cooling extracts heat directly from the stator jacket for sustaining torque output and limiting thermal derating during rapid start–stop or high RMS current profiles. It extends continuous operation margins compared with purely convection-cooled variants in the MHD series.

What does the digital servo feedback (HSF) encoder contribute to control loop fidelity on MHD112D-024-NG2-BN?

The HSF provides high-resolution servo feedback suitable for precise velocity and position regulation for reducing quantization effects in current and speed loops. Its multi-turn absolute variant in the MHD family simplifies homing and enables deterministic restart behavior.

How does the integrated 32.0 Nm holding brake on MHD112D-024-NG2-BN support vertical axes and safety stops?

The brake prevents back-driving under gravity or external torque when drives are disabled for keeping loads stationary during EMO/ESTOP states. It also shortens restart sequences by maintaining axis position until the drive re-energizes.

Why is a plain shaft advantageous versus a keyed output on this product code?

Its plain shaft with appropriate clamping hubs ensures concentricity and minimizes micro-fretting under reversing loads. It also supports higher balance grades at speed for improving servo bandwidth for MHD112D-024-NG2-BN in high-precision motion trains.

How do the mechanical interfaces (192 mm flange, 130 mm pilot) aid retrofit of MHD112D-024-NG2-BN?

Its standardized face-mount geometry and centering diameter align with common IEC-style servomotor adapters for simplifying drop-in replacement. It eases migration for legacy presses, packaging formers and machine-tool axes using earlier Indramat frames.
