3.4.3 CH
[ ]
average time/average number of times/moving average/
time constant settings (Un\G1 to Un\G8)
(1) Set the average time, average count, moving average count or primary delay filter
time constant for each channel for which averaging processing is specified.
(2) To validate the setting, the operating condition setting request (Y9) must be turned
ON/OFF. (Refer to Section 3.3.2.)
(3) 0 is set as the default.
(4) The setting ranges are as follows.
(1) For the time averaging marked
*1
, set a value equal to or greater than (4 times
x 10ms x number of channels used). If any insufficient value is set, an error
occurs and 0 is stored as a digital output value.
(2) For the primary delay filter marked
*2
, set a value equal to or greater than
(10ms x number of channels used). If any insufficient value is set, an error
occurs and 0 is stored as a digital output value.
(3) Writing a value outside the range to a channel will cause an error, storing an
error code in Error code (Un\G19) and turning ON the Error flag (XF). If this
occurs, A/D conversion is performed based on the setting before the error
detection.
(4) Since the default setting is 0, change it for the selected processing method.
(5) If a value is set to a sampling-processing channel, the value is ignored.
