Frequently Asked Questions

What encoder/feedback scheme does the MHD112C-035-PG3-AN use, and why is it advantageous?

It uses digital servo feedback with an integrated absolute encoder that tracks position over more than 4096 revolutions for enabling deterministic multi-turn referencing without homing on power-up. It reduces cycle-time penalties and improves restart reliability on complex CNC/robot axes.

How does the 70 Nm holding brake in MHD112C-035-PG3-AN affect application safety and commissioning?

The electrically released brake provides secure static holding torque during power loss or E-stop for stabilizing vertical or overhauling loads. Its fast actuation permits controlled stops and simplifies safety validation on hoists, Z-axes and pick-and-place stations.

What cooling and sealing features enhance uptime in industrial environments?

Its liquid-cooled housing improves heat extraction for sustaining torque density at low motor frame temperatures under continuous duty. Its plain shaft includes a seal against contaminants for supporting IP-class installations common in printing, packaging and texturing lines.

What’s the continuous stall capability and where is it beneficial?

The motor delivers approximately 38 Nm continuous torque at standstill, supporting precise low-speed contouring without overheating. It benefits rigid tapping, press-feed indexing and registration rollers in converting lines.

How does the “power connection to side A / output connector” affect cabinet layout for MHD112C-035-PG3-AN?

Its side-A power and a dedicated feedback connector allow clean cable routing separate from fluid lines in liquid-cooled builds. It reduces EMI coupling and simplifies strain-relief within compact machine envelopes.
