Precautions during programming
• The control active flag turns ON until the pulse output stops after the execution condition of
F174(SP0H) instruction has turned ON.
• This instruction cannot be executed when a control flag corresponding to each channel is
ON.
• For the FP0H mode, select "Pulse output" for the channel setting corresponding to the
system register no. 402.
• For the FPΣ mode, select "Do not use high-speed counter" for the channel setting
corresponding to the system register nos. 400 and 401.
• When the control code or frequency 1 is any value outside of the settable range, an
operation error occurs. (When the data of the frequency 1 is 0, nothing is executed and the
operation ends.)
• When the frequency after the second step is 0 or outside of the settable range, the pulse
output stops.
• When the table pointer exceeds the area of data registers DT during the pulse output, the
pulse output control will be canceled and the control active flag will turn OFF.
• The target values should be set in the range shown on the next page. If a value outside of
the range is specified, the number of pulses different from the specified value is output.
• For the details of the allocations of I/O and flags, refer to "12.2.2
When
Using Pulse Output Function (FP
Σ Compatible Instruction Mode)".
• For details of the FPΣ mode, refer to "11. FPΣ Mode".
