How does natural convection cooling affect continuous operation?

The system relies on ambient air movement to dissipate heat which limits power density compared to forced cooling. The must therefore be installed in open or ventilated spaces for reliable performance.

Why is the 32.0 Nm continuous torque at standstill important for automation applications?

The allows consistent torque output during static holding or slow positioning operations. The feature ensures stability and precision in high load robotic or CNC systems.

How does the digital servo feedback encoder enhance control accuracy?

The encoder transmits high resolution position data directly to the drive which improves synchronization and speed regulation. The enables faster dynamic response and tighter control loops.

What benefits does the absolute position detection over 4096 revolutions provide?

The feature allows the system to retain position information even after power loss. The eliminates the need for homing cycles which reduces startup time in automated systems.

How does the 70.0 Nm holding brake support safety and stability?

The brake maintains shaft position during power failure or machine shutdown. The prevents mechanical drift in vertical or load bearing installations.
