Frequently Asked Questions

What torque capabilities support both active and static load conditions in the MHD112C-024-NG3-LN?

It provides 38.0 Nm continuous torque at standstill and includes a 70.0 Nm holding brake. This ensures both smooth motion delivery and secure load retention during power-off.

How does the encoder type impact system startup and control precision?

It uses a digital HSF encoder with relative position detection. This requires homing after power loss but supports fine-resolution tracking during dynamic motion control.

How does the LN variant simplify cable routing in industrial cabinets?

Its power connector is oriented to the left (side L). This aids installations where left-exit cabling minimizes interference or supports cleaner panel layouts.

What features contribute to environmental resilience in harsh conditions?

A sealed plain shaft with a shaft seal prevents ingress of dust or fluids. Combined with liquid-cooled housing, it ensures thermal stability and mechanical reliability.

Which form factor and mounting specs aid machine integration?

It features a 192 mm flange and 130 mm centering diameter. These standardized dimensions support compatibility with modular servo platforms.
