F144(Trns) Instruction Specifications; F169(Pls) Instruction Specifications; F168(Spd1) Instruction Specifications; Real Number Calculation Process - Panasonic FP0R User Manual

3. Data size of elapsed value and target value of pulse output and high-speed counter
The data size is changed.
FP0: 24 bits
FP0 compatibility mode: 32 bits
4. F144(TRNS) instruction specifications - Serial data communication
The following 2 items in the specifications for sending data are changed.
1)Processing of starting data of send buffer
FP0: Stores the number of unsent bytes every one-byte transmission.
FP0 compatibility mode: Stores 0 after the completion of all data transmission.
2)Restriction on the number of sent bytes
FP0: No restriction
FP0 compatibility mode: 2048 bytes
5. F169(PLS) instruction specifications - Pulse output (JOG operation)
The following 2 items in the specifications are changed.
1)"Operation mode and direction output" setting process
FP0: "00: No counting mode" is selectable.
FP0 compatibility mode: "00: No counting mode" is not selectable.
Performs the same operation as the one when specifying "10: Incremental counting mode with not
direction output".
2)Pulse width specification
FP0: It is possible to set the fixed pulse width (80μs) or duty ratio.
FP0 compatibility mode: The settings are invalid and the duty ratio of pulse width is fixed at 25%.
6. F168(SPD1) instruction specifications - Positioning control (Home return)
The specifications during pulse output are changed.
FP0 : The elapsed value during home return is not fixed. It becomes zero when home return is done.
FP0 compatibility mode: The elapsed value is counted even during the home return operation. It
becomes zero when home return is done.

7. Real number calculation process

As the accuracy of real number calculation has been improved, the calculation result in the FP0
compatibility mode may differ from the result in the existing FP0 program.
8. Process when a secondary battery is out of charge (T32 type only)
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 data memory will be unstable.
FP0 compatibility mode: The value in the hold area of data memory will be cleared to 0.
