Pulse Output Function
Section 1-5
Note
Stop pulse outputs only when pulses are actually being output. The current
output status can be read from the Pulse Output In Progress Flag (AR 0515 or
AR 0615).
When outputting pulses from an output point, the frequency can be changed
in steps by executing SPED(64) again with different frequencies, as shown in
the following diagram.
Pulses can be output from an output in continuous mode or independent
mode.
Continuous Mode
Pulses are output continuously until stopped with SPED(64) or INI(61).
Independent Mode
The pulse output stops automatically once the number of pulses specified in
SPED(64) have been output. (The pulse output can also be stopped prema-
turely with SPED(64) or INI(61).)
Procedure
Follow the steps outlined below when outputting pulses from a Transistor Out-
put Unit. Pulses can be output from only one terminal on the Transistor Output
Unit at a time.
1,2,3...
1.
Determine the IR word (IR 100 to IR 115) to be used for the pulse output.
2.
Wire the Transistor Output Unit. Wire the terminal corresponding to the bit
that will actually be used in the selected word.
3.
Set the desired IR word address in DM 6615 of the PC Setup. Settings
0000 to 0015 BCD correspond to IR 100 to IR 115. (See page 46 for more
details.)
4.
Program the associated program sections.
a) PULS(65) can be used to set the number of output pulses.
b) SPED(64) can be used to control the pulse output (a pulse output with-
out acceleration or deceleration.)
c)
INI(61) can be used to stop the pulse output.

until the specified number of pulses have
been output (independent mode.)
(Execute PULS(65) and then SPED(64) when
using independent mode.)
