Pulse I/O Board Section 2-2
Note Use INI(61) when pulse output has to be stopped immediately, as for an emer-
gency stop, etc. Pulse output will not stop even if a SPED(64), PLS2(––), or
ACC(––) signal turns input OFF.
Only stop pulse output when it is actually being output. Confirm the status of
pulse output using the Pulse Output In Progress Flag (AR0515/AR0615).
The following table shows the types of frequency changes that can be made
with combinations of PULS(65), SPED(64), INI(61), PLS2(––), and ACC(––).
Frequency change Instruction Operand settings Page
Start pulse output at the specified frequency.
Execute PULS(65) followed by SPED(64).

Change frequency by steps during pulse out-
put.
SPED(64) Port
Continuous/Inde-
pendent Frequency
Stop pulse output with an instruction.
Execute SPED(64) or INI(61).

INI(61) Set control data to
stop pulse output.
Outputs a specified number of pulses. The
pulse output accelerates to the target fre-
quency at a specified rate, and decelerates
to a stop at the same rate.

Outputs a specified number of pulses. The
pulse output accelerates to the target fre-
quency at a specified rate, and decelerates
to a stop at another specified rate.
