9/440 Servo amplifier fault

Posted 19 Feb 2014

Morning, One of my customer have a 9/440 cnc with an "XYZ SERVO AMPLIFIER FAULT" displayed. We have contacted AB France and they told us this product is not supported anymore so they can't help us. We thought that the problem was on the controller itself so we have replaced it with a spare part and we have downloaded AMP and PAL wit ODS software.Unfortunately we still get the error message. The hardware manual say in description column about this error : "This indicates that a fault signal has been received from a servo amplifier.It can usually be corrected by turning off power to the amplifier, and then back on". We did it and we still have the message. The problem is we don't have any servo amplifier option like 3AX-D on the machine so wich servo amplifier is it ??? we have cheked all voltages and connections and everything is ok so we don't know what to do now. Any help will be greatly appreciated. Thanks. JC
