FPΣ/FP−X
Precautions during programming
During the time that the circular interpolation control flag R904E is on, the pulse output instructions F166 to
F176 cannot be executed.
When using this instruction for FPΣ, the setting for the channels corresponding to system registers no. 400
and no. 401 should be set to "High−speed counter not used".
When using this instruction for FP−X, set the pulse output by the system register.
If a rewrite is executed during RUN while the system is operating, pulse output stops while the program is
being rewritten.
If the same notation is being used for both the ordinary program and the interrupt program, make sure they
are not both executed at the same time.
Target value setting can be used in FPΣ V1.4 or more and FP−X only.
If a value outside of the specified range is written for the frequency area while the instruction is being
executed, the frequency output will be adjusted to either to the minimum or the maximum. And when starting
execution of the instruction, an operation error occurs.
If the control code is changed after the instruction startup, it will be invalid.
If the frequency is changed to a value outside the specification range after the instruction startup, an
operation error will not occur and the program will run at the minimum or maximum value in the specification
range.

Turns on when:
Turns on when:
− The control code or frequency is outside the specification range. (During
instruction startup)
− The specified area is exceeded when an index is modified.
− The "n" is outside specification range.
− With the FP−X, the pulse output has not been set by the system register.
