Conversion data
Note
Output Point 3
The output ramps make output signals gradually change with time to prevent
sudden changes in response to Conversion data fluctuations. The time required
to change the present value to a new value is set in ms. This function can be set
individually for each output point.
When an output signal reaches the new value after the ramp set time elapses,
the output signal holds that value if there is no new change in the conversion
data. Therefore, when using this function, change conversion data only if output
needs to be changed.
To enable the output ramp function, set the output ramp set time, turn ON the
Output Ramp Enable Bit, and turn ON the Parameter Update Bit in the allocated
I/O words. Conversion data in RAM will be rewritten and the Analog Output Unit
will generate output signals according to the new parameter settings.
Set the output ramp set time in ms. The setting range depends on the data for-
mat (BCD or binary mode) as shown in the following table. The output ramp set
time must be 8 ms or greater.

output signal to reach a new value is a multiple of 8 ms. Therefore, the maxi-
mum output ramp set time accuracy is + 8 ms.
