Centroid CNC control sales, service, training and support
The most basic maintenance should be obvious: keep it clean. Clean off the chips, wipe down the table, sweep the floor, etc..
This procedure is recommended every 2-3 years for all M10, M20, M40, M50, M60, M39 and early M400 controls. This will fix and/or prevent intermittent jerks and "full power w/o motion" and "position error" stalls.
How to make and use a test device for Centroid DC-servo encoders.
Tips and procedures for isolating position loss issues, including mechanical slippage, encoder failures, and programming errors.
How to interpret the red and green status LEDs on an RTK2 PLC Unit.
Using the Yaskawa drive monitoring modes to measure torque load.
This procedure is needed if you have a pre-2002 4-axis control, wired for a rotary table with a 24VDC clamp solenoid coil, and you want to use a current Centroid rotary table which has a 120VAC clamp solenoid.
This diagram shows wiring connections to convert an early 1994 Supermax M50 to use a GS3 inverter and programmable spindle speed, using the SPINOVER board connected to the original 15/15 PLC.
This conversion could also apply to 1997-2001 M39 controls which used the same PLC board.
This procedure explains issues you may encounter if you need to replace the DC3IO combined servo drive and PLC unit in an existing control with the newer (2009 and later) DC3IOB unit.
