5. F169_PulseOutput_Jog, JOG operation
There are two differences between the FP0 and the FP0R specifications:
Count mode: The FP0R does not support the "no counting" setting. Instead,
incremental counting is performed with the FP0 pulse output instructions set to "no
counting".
Pulse width specification: In the FP0 compatibility mode, the duty ratio is fixed at 25%.
Differing settings in the FP0 programs will be ignored.
6. F168_PulseOutput_Home, Home return
In FP0 compatibility mode, the elapsed value is counted during home return
operations. With the FP0, the elapsed value is indefinite. In both cases, the elapsed
value will be reset to 0 when home return has been completed.
7. Real number calculation process
Since the accuracy of real number calculation has been improved, the calculation
results obtained in the FP0 compatibility mode may differ from the results obtained in
the existing FP0 program.
8. If the secondary battery installed in the T32 type is out of charge, the next power-on
process will be different:
FP0: The value in the hold area of the data memory will be unstable.
FP0 compatibility mode: The value in the hold area of the data memory will be cleared
to 0.
9. The sampling trace function is not available in FP0 compatibility mode.

FP0
The send buffer stores the number of
bytes to be sent. This number is
decremented after every 1-byte
transmission.
None
FP0 compatibility mode
The number of bytes to be sent remains
unchanged during transmission. After
transmission has been completed, 0 is written
to the send buffer.
2048 bytes
