1.5.6 Cautions on use of a personal computer and the FX-20P-E
• Only the program transfer function is available from a personal computer or the FX-20P-E to
the FX
2N
-1RM. The monitor function, the test function, the current value change function,
etc. are not available. (If such a function is used, a communication error occurs.)
Set the parameter as shown in the table below when transferring programs.
If a program is transferred while the parameters are not set as shown above, a parameter
mismatch error or program mismatch error occurs.
• Use a personal computer or the FX-20P-E only when FX
2N
-1RM is in PRG mode (halt condition).
The following may occur if they are used in RUN mode:
- FX
2N
-1RM is overloaded because the power is also supplies the peripheral equipment
and the FX
2N
-1RM stops.
- Communication between the peripheral equipment and FX
2N
-1RM becomes very slow
and a communication error takes place.
• When a program is transferred from a personal computer or the FX-20P-E, D1000 to D7143
correspond to BFM #1000 to BFM #7143, D7144 to D7145 correspond to BFM #0 to BFM
#1, and D7146 to D7159 correspond to BFM #13 to BFM #26.
At this time, the angle data and FNC instructions (FNC70 to 75, 90) among D1000 to D7159
are fixed to a double value (720 degrees/rotation) without regard to the setting of the
resolution (selected by the data setting panel or BFM #0 b6).
D7144 (BFM #0), D7146 (BFM #13) and D7148 (BFM #15) are treated by one time value.

, D1000 becomes 200.

×
2 = 2140
When FNC 70 (BCD output) is set, D1000 becomes 2140. Continuing D1001
reaches twice value at strobing ON time.
When individual automatic angle advance function is set, D6376 to D6393 reach
the value twice the number of rotations, the turning ON angles, and the turning
OFF angles of S0 to S6.
