Common faults
What usually fails on a unit like the 3HAC026846-001 IRC5
CNC controls combine a computer, operator display, I/O and axis drives. Faults in any one stop the machine, and the parameters and machine data have to survive the repair. Control units, displays, I/O boards and amplifiers can be repaired at board level.
Control unit won't boot
Power supply faults, a flat backup battery or corrupted memory stop the control at power-up.
Display and keyboard faults
Dead or dim displays, failed CRT-to-LCD units and unresponsive operator keys.
Axis and spindle amplifier alarms
Overcurrent, overload and feedback alarms from the amplifiers or the motors they drive.
I/O link and interface faults
Loss of communication with machine I/O, causing emergency-stop or ready alarms.
Lost parameters
Machine data lost through a failed battery or memory, leaving axes unconfigured.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Record all alarm numbers shown on the screen.
- Keep the backup battery fresh, and change it with the control powered on where the maker says to.
- Back up parameters, programs and PLC data while the control works.
Leave to a specialist
- Restoring machine data and parameters.
- Board-level repair of control units and amplifiers.
- Reference-point and axis set-up after a repair.
