Frequently Asked Questions
Q: What is the main advantage of the 24-bit encoder?
A: The 24-bit resolution (16,777,216 pulses/rev) provides exceptional positional accuracy, enabling sub-micron positioning and smooth low-speed operation--critical for high-precision applications like semiconductor manufacturing and CNC machining.
Q: Is the brake suitable for stopping a moving load?
A: No, the brake is designed for holding stationary loads only. For dynamic braking, use the regenerative braking function of the ASDA-B3 drive.
Q: What is the IP rating of this motor?
A: The motor achieves IP65 protection when used with waterproof connectors and the integrated oil seal, making it resistant to dust and water jets.
Q: Which servo drive should I use with this motor?
A: The motor is designed for Delta ASDA-B3 series drives (ASD-B3-1021-L/M/F/E) for optimal performance and full feature utilization.
Q: What applications is this motor best suited for?
A: The medium inertia design with brake makes it ideal for vertical axis applications, robotic arms, CNC machinery, and any application requiring precise positioning with holding capability.
Q: Does this motor require a separate battery for encoder position retention?
