PMC OPERATION (CRT/MDI)
424
Note the followings when you input PMC–address on the original MDI
boards made by MTBs without using Standard MDI Unit supplied by
FANUC.
(1) If the MDI has the keys to input PMC–address (X, Y, F, G, R, A, C,
K, D, T), You can operate as same as FANUC Seires 18
(PMC–SA1/SA3).
(2) If MDI does not have those keys, input PMC–address as follows.
When inputting PMC–address (in PCLAD, STATUS and so on), you
can substitute number keys (0 to 9) and a hyphen key (–) for
PMC–address capital keys (X, Y, F, G, etc.). PMC–address capital
keys are corresponding to the number keys as follows.
PMC–address keys
G F Y X A R T K C D
number keys
0– 1– 2– 3– 4– 5– 6– 7– 8– 9–
(Example) If you want to input “X0.0 [SRCH] ”, input “3–0.0 [SRCH] ”.
When a valid sequence program is contained in the PMC, automatic
operation can be started immediately after power–on by keep relay
setting. This eliminates the need to display the PMC screen and run a
sequence program each time the power is turned on. The keep relay
setting method depends on the PMC model. See Section 4.3.3.
When the power for the CNC is turned on for the first time, a RAM
PARITY or NMI alarm may occur in the PMC. This is caused by invalid
data in the sequence program storage area in the PMC. The sequence
program must be cleared to prevent this.
The automatic operation (see 1.2 above) can also be stopped by clearing
the sequence program in the PMC.
The sequence program can be cleared in either of the following two ways:
1. Turn on the power while pressing X and O.
2. Turn on the power, display the PMC screen, and use the programmer
function of the PMC (EDIT/CLEAR).
NOTE
In case of loader control function, turn on the power while
pressing X and 5.
