What cooling system reduces upkeep?

It relies on natural convection cooling. By avoiding external fans, the design eliminates common failure points and prevents dust or debris from being pulled inside.

How does Side B orientation support dense panels?

The Side B connection allows cleaner cable routing and easier access for checks or servicing, reducing repair time in tight enclosures.

What connector type supports consistent wiring?

It uses a standard flange connector, enabling the use of pre-assembled harnesses for repeatable terminations and reliable strain relief.

How is shaft retention ensured during power loss?

A 22 Nm holding brake secures the axis when de-energized, preventing drift and protecting both tooling and workpieces.

What feature guarantees coaxial mounting accuracy?

A 130 mm centering diameter provides precise alignment for attachments, minimizing vibration and extending the life of couplings and bearings.
