 FP-X: When a pulse output instruction is executed and pulses are being output,
the pulse output control flag (e.g. sys_bIsPulseChannel0Active) of the
corresponding channel is TRUE. No other pulse output instruction can be
executed as long as this flag is TRUE.
 FP: The high-speed counter control flag (e.g.
sys_bIsHscChannel0ControlActive) and the pulse output control flag (e.g.
sys_bIsPulseChannel0Active) are assigned to the same internal relay (e.g.
R903A). Therefore, when a high-speed counter instruction or a pulse output
instruction is executed, both the high-speed counter control flag (e.g.
sys_bIsHscChannel0ControlActive) and the pulse output control flag (e.g.
sys_bIsPulseChannel0Active) for the channel used are TRUE. No other
high-speed counter instruction or pulse output instruction can be executed as
long as this flag is TRUE.
 FP: Executing the circular interpolation control instruction F176 sets the circular
interpolation control flag (sys_bIsCircularInterpolationActive) to TRUE. The status
of this flag is maintained until the target value is reached (even if the execution
condition is no longer TRUE). During this time, other pulse output instructions
cannot be executed.
 When programs are being edited in RUN mode, pulse output stops but resumes
after the program changes have been downloaded.
 FP: Set any high-speed counter allocated to a pulse output channel to "Unused"
in the system registers.
 FP-X: Set "Pulse output" for the desired channel in the system registers.
We strongly recommend that you incorporate a forced stop (see page 1021)

option in your positioning program.
The status of the high-speed counter control flag or pulse output control flag may

change while a scan is being carried out. For example, if the flag is used more
than once as an input condition, different statuses may exist within one scan. To
ensure proper execution of the program, the status of the special internal relay
should be copied to a variable at the beginning of the program.

Description for FP0R
Use the following predefined DUT:
F171_PulseOutput_Trapezoidal_Type0_DUT (maximum speed = first target speed) or
F171_PulseOutput_Trapezoidal_Type1_DUT (maximum speed = 50kHz).
The target speed can be changed during pulse output. Two control methods are available:
 Type 0: The speed can be changed within the range of the target speed specified
first.
 Type 1: The speed can be changed within the range of the maximum speed
(50kHz).
