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(––).
