Yaskawa Motoman has updated its digital interface for Miller Electric Mfg. Co. Auto-Axcess power sources to include the new Auto-Axcess E digital series power sources. Thousands of Motoman robots were sold with Miller Auto-Axcess and Auto-Axcess DI power sources that utilized analog or DeviceNet digital interface. The analog interface is easy to retrofit to older robots. With the DI, the robot teach pendant can be used to change power source program data normally limited to Miller’s File Manager application.
The Auto-Axcess E digital power source uses an Ethernet interface and allows control of weld data monitoring parameters through the Insight Centerpoint application. The robot program communicates the part number and weld ID to Insight Centerpoint, which tracks the weld data and verifies it is within limits. Miller’s Insight Centerpoint weld process management system can also be used to track weld quality and overall equipment effectiveness (OEE).
The robot’s actual travel speed is monitored by Insight Centerpoint so that heat input can be measured and maintained. Process control has been improved with the ability to change pulse slope and arc control in real time. The Ethernet interface can be networked allowing up to four robots to operate from a single connection. Computers can be added to the network to manage the weld data with the Insight Centerpoint application. Like Auto-Axcess DI, the Miller Auto-Axcess E digital is available in 300, 450 and 675 amperage capacities.
