Pulse I/O Board

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
Start pulse output at the specified frequency.
Execute PULS(65) followed by SPED(64).
Change frequency by steps during pulse out-
put.
Stop pulse output with an instruction.
Execute SPED(64) or INI(61).
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.
ACC(––) instruction mode 0: Acceleration +
Independent Mode
Execute PULS(65) followed by ACC(––).
Accelerates pulse output from the current
frequency to the target frequency at a speci-
fied rate.
Pulse output will continue.
Execute PULS(65) followed by ACC(––).
ACC(––) instruction mode 1: Acceleration +
Continuous Mode
Decelerates pulse output from the current
frequency to the target frequency at a speci-
fied rate.
Pulse output will stop when the specified
number of pulses have been output.
Execute PULS(65) followed by ACC(––).
ACC(––) instruction mode 2: Deceleration +
Independent Mode
Decelerates pulse output from the current
frequency to the target frequency at a speci-
fied rate.
Pulse output will continue.
Execute PULS(65) and then ACC(––).
ACC(––) instruction mode 3: Deceleration +
Continuous Mode
