Overview

The VPL-B0631U-CJ12AS voltage level is 480V AC, uses a U-shaped winding design, and the rated speed can reach 8000rpm; the base has a 63mm bolt hole spacing specification and is only equipped with 1 core lamination. The motor adopts a keyway shaft design, equipped with Speedtec right-angle DIN connector, has no brake configuration, and is adapted to IEC metric mounting flange. Some versions also have an IP66-rated shaft seal, and the protection performance is suitable for industrial environments.

FAQ:

1.What is the mounting flange standard for the 63mm base of VPL-B0631U-CJ12AS?

The mounting flange standard corresponding to the 63mm base of VPL-B0631U-CJ12AS is IEC metric type FF (free mounting hole).

The product manual of the Kinetix VP series low-inertia servo motors clearly states that the FF-type free mounting hole design can adapt to most load connection requirements that comply with IEC metric specifications in industrial scenarios. At the same time, the flange size of this standard is also consistent with the installation specifications of the 063mm frame size servo motors of the same series, making assembly and accessories universal.

2.What kind of control accuracy can the 18-bit single-turn feedback encoder of VPL-B0631U-CJ12AS achieve?

VPL-B0631U-CJ12AS 18-bit single-turn encoder accuracy:

Resolution: 2^18=262144 points/circle, minimum resolution angle≈0.00137° (4.93 arc seconds);
Repeat positioning accuracy: ≤±2Bit (±0.00274°);
Adaptable scenarios: high-speed/precision positioning (assembly lines, machine tools), matched with Kinetix drives to achieve precise control.

3.VPL-B0631U-CJ12AS is designed without a brake. What external accessories should be used in vertical load scenarios?

VPL-B0631U-CJ12AS (without brake) necessary accessories for vertical load:

Core: External electromagnetic power-off brake (fail-safe type, optional redundant double brake);
Auxiliary: precision reducer (increases torque and stabilizes speed) + elastic coupling (ensures coaxiality);
Safety: safety module (monitoring of holding brake status, in accordance with EN ISO 13849);
Optional: manual release device (debugging and maintenance), seal (protection).
