SGDB-05VN - Yaskawa SGDB-05VN MECHATROLINK servo pack

Evidence-backed servo drive role for SGDB-05VN, with explicit installation boundaries.

Documented function

Rebuilt from individual evidence

System position

Unknown: Evidence boundary

The exact-reference listing identifies SGDB-05VN as a Yaskawa SGDB AC servo drive rated at 0.5 kW with a 200 V supply and MECHATROLINK command interface.

Yaskawa's SGDB documentation shows the SERVOPACK receiving network or reference control and connecting to the servomotor and encoder.

The drive sits between the upstream controller and the matched servo motor in the documented axis.

The drive converts controller references into controlled electrical output for the matched servo motor.

Unknown: The installed motor pairing, network configuration, firmware, and machine load are not established by the captured sources.

Exact reference: SGDB-05VN

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Drives a matched SGMG servomotor from MECHATROLINK motion commands.
System position: Sits between the MECHATROLINK controller and the matched SGMG servomotor.
Upstream / inputs: Receives MECHATROLINK command data and encoder feedback through the SGDB servo system.
Downstream / outputs: Supplies controlled electrical output to the matched servomotor.
Limitations: Unknown: The installed motor pairing, network configuration, firmware, and machine load are not established by the captured sources.
