FAQ

• Q: How many axes does DSQC 236G control? A: Each DSQC 236G controls one servo motor axis. A typical 6-axis robot requires six drive boards.
• Q: What is the difference between DSQC 236G and DSQC 236T? A: DSQC 236G (YB560103-CD) is for S4 controllers, while DSQC 236T (YB560103-CE) is for S3 controllers with 380-480V AC input. They are not interchangeable.
• Q: Can DSQC 236G be used in S4C+ or IRC5 systems? A: No, DSQC 236G is specific to S4 controllers. S4C+ uses DSQC 345/346/358 series, and IRC5 uses DSQC 651/652/663.
• Q: What feedback type does it use? A: DSQC 236G uses resolver or encoder feedback for closed-loop position control. Verify your motor feedback type before installation.

Installation Guide

1. Power off the S4 controller and disconnect 3-phase mains. Lock out/tag out.
2. Wait 10 minutes for DC bus capacitors to fully discharge.
3. Identify the failed axis drive slot and document all cable connections.
4. Remove the existing DSQC 236G from the drive rack.
5. Install the new board in the same slot, ensuring proper backplane connection.
6. Connect servo motor power cables and feedback cables.
7. Verify all connections are secure and properly polarized.
8. Restore power and perform axis calibration via the teach pendant.

Selection Tips

• Use DSQC 236G (YB560103-CD) for S4 controller servo drive replacement.
• Match the exact board revision (e.g., /22, /24, /26, /28, /29) to your controller firmware.
• Replace drive boards in complete sets when multiple axes show degraded performance.
• Verify motor compatibility (orange series vs. other series) before ordering.
