(2) Trouble mode process
The machine can be operated under some conditions.
Operations except for the trouble mode are enabled (READY). For the
modes which cannot be operated, only setting is enabled and a mes-
sage is given to show the operations are disabled. (NOT READY in this
case)

(3) Writing to the trouble memory
In case of a same trouble in this machine, selection is made with the
simulation to write into the trouble memory or not. If this simulation is
set, any trouble is written into the trouble memory unconditionally.
simulation to write into the trouble memory or not. If this simulation is
set, any trouble is written into the trouble memory unconditionally.
(SIMULATION. 26-35)
0: A same trouble as the previous one is not written. (Default)
1: Any trouble is written into the trouble memory unconditionally.
B. Power ON trouble detection sequence.
• When the power is turned ON, if H3, H4, H5, U1, U2, PF, L4-31, F3-12/22, or U6 (LCC-related sub code 09 only) is saved, a trouble code is imme-
diately displayed. E7 (50, 55, 56, 57, 60, 65, 66, 67) trouble is not saved.
