backup battery voltage The PG cable was disconnected from the
controller.
Absolute reset has not been executed after the
initial setup.
The voltage of the absolute-data backup battery
has dropped. Connect the PG cable to the controller and execute an absolute
reset.
Replace the absolute-data backup battery and execute an
absolute reset.
CA5 Stop deviation overflow error Operation is mechanically disabled.
If there is no problem in the mechanical
function, the power stage board is faulty. Check to see if the actuator mounting bolts are contacting inside
the axes, or if the slider attachment is contacting any
surrounding mechanical parts.
Replace the board.
C6b Deviation overflow error Operation is mechanically disabled. Check to see if the actuator mounting bolts are contacting inside
the axes, or if the slider attachment is contacting any
surrounding mechanical parts.
