Integration Expertise & FAQs

What Sigma-7 servo drive is compatible with this motor?

The Yaskawa SGM-08U3B4L pairs perfectly with Yaskawa's Sigma-7 series drives, such as the SGD7S-200A10A. The drive automatically recognizes the motor's high-resolution 24-bit encoder for optimal tuning and performance.

How does the 24-bit encoder benefit my application compared to a lower-resolution one?

The ultra-high 24-bit resolution provides extremely fine position data. This enables smoother low-speed rotation, minimizes velocity ripple, and allows for more precise positioning. It is critical for applications like semiconductor manufacturing or high-accuracy CNC indexing.

Can I operate this motor at its maximum speed of 5000 RPM continuously?

No, the rated continuous speed is 3000 RPM. You can use the 5000 RPM maximum for short durations, but sustained operation at higher speeds requires torque derating. Consult the speed-torque characteristic curve in the manual for safe operating limits.

What does the “U3B4L” suffix in the model number specifically indicate?

This suffix code defines key options: 'U' for voltage class, '3' for winding type, 'B' for shaft and key specifications, and '4L' for the feedback type (24-bit incremental encoder) and connector style. Always verify the exact configuration against the factory datasheet.

What is a critical electrical consideration during installation?

Ensure proper grounding and use shielded motor cables. Run the motor power cables and encoder feedback cables separately from high-voltage AC lines. This practice minimizes electrical noise interference, which can cause erratic motion or communication errors with the drive.
