High-speed Counter/Pulse Output Instructions Section 3-20
■ Changing a PV (C = 0002 hex)
If C is 0002 hex, INI(880) changes a PV as shown in the following table.
■ Stopping Pulse Output (P = 0000 to 0003, 1000, or 1001 hex and C = 0003
hex)
If C is 0003 hex, INI(880) immediately stops pulse output for the specified
port. If this instruction is executed when pulse output is already stopped, then
the pulse amount setting will be cleared.

The present value of the
pulse output is changed.
The new value is speci-
fied in NV and NV+1.
Note This instruction
can be executed
only when pulse
output is stopped.
An error will occur
if it is executed dur-
ing pulse output.

The present value of the

for the instruction if
the specified port
is not set for a
high-speed

Note An error will occur
if a value outside

Name Label Operation
Error Flag ER ON if the specified range for P, C, or NV is exceeded.
ON if the combination of P and C is not allowed.
ON if a comparison table has not been registered but
starting comparison is specified.
ON if a new PV is specified for a port that is currently out-
putting pulses.
ON if changing the PV of a high-speed counter is speci-
fied for a port that is not specified for a high-speed
counter.
ON if a value that is out of range is specified as the PV for
an interrupt input in counter mode.
ON if INI(880) is executed in an interrupt task for a high-
speed counter and an interrupt occurs when CTBL(882)
is executed.
ON if executed for a port not set for an interrupt input in
counter mode.
