Description

The DSQC345B is a compact yet powerful Servo Drive that provides precise and reliable control for AC servo motors, with a control loop frequency of 1 kHz, a position resolution of 0.1 µm, and a speed resolution of 0.01 mm/s. It can be used with a variety of ABB industrial robots and is suitable for various robotic applications such as material handling, assembly, machine tool tending, arc welding, and palletizing. It is easy to install and configure, and is robust and reliable, capable of withstanding harsh industrial environments.

Applications

Automobile manufacturing plants: Used for spot welding, arc welding, and parts handling.

Electronics assembly plants: Used for precision gluing and parts fastening.

Food packaging plants: Used for high-speed palletizing and sorting.

Metal processing plants: Used for CNC machine tool loading and unloading and grinding.

Troubleshooting

Servo Communication Error: The teach pendant reports an "Axis Computer Failure." Check for oxidation on the board's gold fingers or replace with a spare.

Path Deviation: The robot's path is inaccurate. This may be due to aging of the DSP processing unit on the board or deterioration of the electrolytic capacitors.

Loss of All-Axis Feedback: An error message indicates that all axis positions cannot be read. Check the connection between the DSQC345B and SMB.

Status LED Red: The internal logic circuitry of the board is damaged. This usually requires repair or replacement of the entire board.

FAQ

Q: Can the DSQC345B be directly connected to 380V household power?
A: No. The DSQC345B requires a specific DC or AC supply generated through a transformer and rectifier module (such as the DSQC346 series) inside the robot control cabinet.

Q: What does a flashing red LED on the DSQC345B drive mean?
A: It usually indicates an internal fault or communication interruption. You need to check the specific error code via the teach pendant’s error log.

Q: Can I replace the DSQC345B with a different model, for example, a DSQC345A?
A: Not recommended. The DSQC345B version typically includes circuit or firmware optimizations, so compatibility and parameter configuration must be verified before replacement.

Q: What if the DSQC345B drive has no output but no alarm messages?
A: Check whether the enable signal is active and confirm that the controller has issued motion commands to the drive layer.

Q: Which motor types does the DSQC345B support?
A: The DSQC345B is mainly compatible with ABB synchronous AC servo motors, with parameters predefined in the S4C+ system.
