Product Description

The 6369901-104, also known as the DSQC104, is a resolver-to-digital conversion board used in ABB industrial robot controllers. It interfaces directly with motor-mounted resolvers to convert analog sine/cosine feedback signals into precise digital position data for the motion control system. This enables high-accuracy joint positioning and dynamic trajectory tracking in robotic arms.

Mounted inside the robot’s drive or controller cabinet, the DSQC104 ensures reliable signal conditioning, noise rejection, and real-time angle calculation—critical for maintaining repeatability in welding, assembly, and material handling applications.

Typical Applications

Joint feedback processing in 6-axis articulated robots
Retrofit or repair of resolver-based servo systems
Replacement for failed DSQC104 units in production cells

FAQ
Q: Is this board compatible with encoder-based motors?
A: No—the DSQC104 is designed exclusively for resolver feedback. Encoder-based axes use different interface boards (e.g., DSQC534 or DSQC633).

Q: Can it be calibrated in the field?
A: Basic offset calibration is handled automatically by the robot controller during startup. Full resolver alignment requires ABB service tools and mechanical zeroing.

Q: What happens if the DSQC104 fails?
A: The affected axis typically reports a “Resolver Fault” or “Position Error,” and motion is disabled for safety. Replacement restores full functionality.
