High-speed Counter/Pulse Output Instructions
■ Starting Comparison (C = 0000 hex)
If C is 0000 hex, INI(880) starts comparison of a high-speed counter's PV to
the comparison table registered with CTBL(882).
Note A target value comparison table must be registered in advance with
CTBL(882). If INI(880) is executed without registering a table, the Error Flag
will turn ON.
■ Stopping Comparison (C = 0001 hex)
If C is 0001 hex, INI(880) stops comparison of a high-speed counter's PV to
the comparison table registered with CTBL(882).
■ Changing a PV (C = 0002 hex)
If C is 0002 hex, INI(880) changes a PV as shown in the following table.

or 0103 hex)
■ Stopping Pulse Output (P = 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.
Operation
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
during pulse output.
Differential The present value of the
inputs, high-speed counter is
increment/ changed. The new value
decrement is specified in NV and
pulses, or NV+1.
