Pulse output instructions
Target value match stop mode (type 1): Output stops when the target value is

reached. Set this mode in the control code, and specify the target value (an
absolute value) in the DUT. (FP V1.4 or higher, FP-X)

General programming information
!
 If both the main program and the interrupt program contain code for the same
channel, make sure both are not executed simultaneously.
 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.
 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.
If the execution of the instruction is started with an invalid frequency value, an

operation error occurs. If the frequency is changed to an invalid value during
execution of the instruction, the frequency output will be adjusted to either the
minimum or the maximum value of the permissible range.
 Changing the control code during execution of the instruction will have no effect.
 We strongly recommend that you incorporate a forced stop (see page 1021)
option in your positioning program.

Warning!
As soon as you begin editing a program online (i.e., in
RUN mode) using this instruction, pulse output will
stop.
