Pulse Output Function
This section explains the settings and methods for using the CQM1H pulse
output function. Refer to the
CQM1H Operation Manual
for details on hard-
ware connections to output points and ports.
Standard pulses can be output from a Transistor Output Unit’s output using
SPED(64). Pulses can be output from just one bit at a time. The duty factor of
the pulse output is 50% and the frequency can be set from 20 Hz to 1 kHz.
Pulse Output Operations
The following table shows the pulse output operations that can be made with
combinations of PULS(65), SPED(64), and INI(61).
Note
A Transistor Output Unit must be used for this application.
