When an error occurs
When the value to be output is out of the output range, an error occurs. The error code (191H) is stored in 'Latest error code'
(Un\G0), 'Error flag' (XF) turns on, and the ERR LED turns on. When an 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 an error (error code: 191H) has occurred, correct the digital input value of the wave data so that the value is within the
output range. Then, turn on and off 'Error clear request' (YF).

In addition, when the digital input value out of the range is set and an error (error code: 191H) has occurred, correct the
value to the one within the range and turn on and off 'Error clear request' (YF).
To check the buffer memory address where the wave data with the value out of the range is registered, use Wave output
digital value out-of-range address monitor.

(1): If the value to be output is smaller than the minimum value of
the output range, the analog output value is the minimum value
of the output range.
(2): If the value to be output is greater than the maximum value of
the output range, the analog output value is the maximum value
of the output range.
