We have a problem with our Sabre 2000 in that when the machine power is applied, after the control has booted, the axis all begin to move slowly and a drive overload alarm is displayed immediately. This happens even with the federate override set to 0.
If I remove the C1 connector, which includes the command signal wires, from the x axis the machine powers up normally and no axis move then after a few seconds there is a drive not enabled fault as the connector also contains the enable signal wire.
If I remove the C1 connector from the y or z axis the machine powers up but the two axis that are still connected move slowly as before but this time there is no overload alarm just the drive not enabled alarm after a few seconds due because C1 is disconnected.
Has anyone seen this issue or can anyone offer any advice what to test to try to find the problem?
