The 3HAC036260-001 is mdu-430c low-voltage main drive unit used in ABB IRC5 Compact robot controllers. It provides the principal motor-drive power stage inside the compact controller.
Confirm the IRC5 Compact controller, robot model, drive-system generation and installed power-stage connections. The full 3HAC036260-001 article number and the installed controller nameplate should be compared before a purchase order is released.
Follow the ABB controller service instructions and verify controller isolation, DC-link discharge, internal wiring, cooling path and mechanical mounting. Any cable, busbar, harness, fan lead, or mounting hardware must be identified separately unless included in the quotation.
DSQC431 / MDU-430C Main Drive Unit identified in the IRC5 Compact spare-parts list. Use the ABB article number and DSQC/type designation together when reviewing a replacement.
Engineering check: Confirm 3HAC036260-001 is the DSQC431 / MDU-430C low-voltage main drive for the installed IRC5 Compact controller. Match supply class, motor phases, brake and feedback connectors to the cabinet drawing.
Acceptance test: After safe isolation and reconnection, enable the drive in service mode and jog each assigned axis at reduced speed. Verify DC-link status, motor direction, feedback, current balance and the absence of drive or thermal alarms.
