operated as usual.

displayed on the operation panel. These are

4.1.2 SC CODE DESCRIPTIONS
If a problem concerns a circuit board, disconnect and reconnect the connectors
and then test the machine. Often a loose or disconnected harness is the cause of
the problem. Always do this before you decide to replace the PCB.
If a motor lock error occurs, check the mechanical load before you decide to
replace the motor or sensors.
