When an error occurs
When a value out of the setting range is tried to be output, a digital value setting range error (error code: 191H) occurs.
When a digital value setting range error (error code: 191H) occurs during the wave output, the analog output value becomes
as follows.
• If the value to be output is greater than the maximum value of the output range, the maximum value of the output range is
output in analog.
• If the value to be output is smaller than the minimum value of the output range, the minimum value of the output range is
output in analog.
When a digital value setting range error (error code: 191H) has occurred, correct the digital value of the wave data so that
the value is within the output range. Then, turn on and off 'Error clear request' (YF).
• When the output range is set to "0 to 5V":

(1) A digital value setting range error (error code: 191H) occurs.
(2) If the value to be output is smaller than the minimum value of the output range, the minimum value of the output range is output in analog.
(3) If the value to be output is greater than the maximum value of the output range, the maximum value of the output range is output in analog.
To check the buffer memory address where the wave data with the value out of the range is registered, use 'CH1 Wave output
digital value outside the range address monitor' (Un\G440, Un\G441).
