Frequently Asked Questions
How does digital servo feedback improve motion accuracy?
The digital feedback ensures precise rotor position detection for accurate control. The system minimizes lag and maintains stable synchronization during dynamic motion.
Why is a plain shaft design preferred in certain automation setups?
The plain shaft allows easy coupling with different mechanical systems. The design supports flexible alignment without adding mechanical backlash.
What are the installation benefits of the side B power connector orientation?
The side B connector provides convenient cable routing in compact enclosures. The layout simplifies maintenance and minimizes wiring interference.
How does continuous torque at standstill affect servo stability?
The high torque at standstill maintains steady holding power under load. The performance reduces drift and enhances precision during static positioning.
What role does the flange size play in system compatibility?
The flange size determines the motor’s mechanical fit with mounting interfaces. The 192 mm frame supports compatibility with heavy-duty drives and automation systems.
