The instruction is exclusive to the PU modules at the right of the PLC and is not applicable to the PU modules at the
right of the remote module. If the specified module is not a PU module, the error flag Error will change to ON.
3. Axis sets the output axis number for the specified PU module. The setting values 1~4 represent the axis1~axis4
output of the specified PU module respectively. If the PU module has no corresponding axis number for output, the
error flag Error will change to ON.
4. TarPulse sets the number of output pulses. The pulse number is a positive signed 32-bit value. When the value is
0, it means the output is always being performed, the number of output pulses is not limited and the output is not
stopped until the instruction is disabled. When the value is less than 0, the PLC automatically uses 2s complement
to transform the value into a positive integer as the number of output pulses.
5. TarSpeed sets the target output speed (Unit: Hz). The input value is a signed 32-bit. You can modify the target
frequency any time after the instruction is enabled and the PU module will automatically switch to the newly set target
frequency after outputting a full pulse.
Note: Before the target frequency is changed, please take into consideration whether the modified speed and PLC
scan time match or not.

6. When TarSpeed is a positive number (>0), it means that the "positive direction" output point is Off. When TarSpeed
is a negative number (<0), it means that the "negative direction" output point is On. When TarSpeed is 0, it means
that the output will be paused after the being executed pulse is output fully.
7. The instruction does not support the function of acceleration and deceleration. Use the DPUDRI instruction instead
if you need the function of acceleration and deceleration.
8. The instruction can be used for the speed change. While the instruction is being executed, you can change the value
of TarSpeed so as to change the output speed.
9. When the outputs have reached the pulse number specified by TarPulse, the Done flag changes to ON. The Done
flag need be cleared by manual. The instruction sets the completion flag to ON only when the output is completed.
10. If any error occurs as the instruction is in process of the output, the Error flag changes to ON. Refer to the error
codes ErrCode shows for the trouble shooting.
The error codes that ErrCode shows are listed in the following table.
TarSpeed Setting Range
-200,000 (-200K) ~ 200,000 (200K)
-100,000 (-100K) ~ 100,000 (100K)
