4) The actual minimum output frequency (that is, the minimum base output frequency) is
calculated according to the following formula:
Vset(Hz)
2×Tacc (ms)/1000
Vmin=
5) The number of output pulses can be increased or decreased during instruction execution.
Before modifying the number of output pulses, you need to set the "pulse modication valid ag bit" (M8350,
M8370, M8390, M8410, or M8430; default: OFF) of special elements. See the following table.

6) You can enable the ag bit to release the high-speed output port resources, so that the next
pulse output instruction is started immediately without disabling the previous instruction ow.
The "port output initialization ag bit" of special elements must be set. See the following table.

If the ow of the pulse output instruction A is active, the instruction occupies the high-speed output port no
