■When an error occurs
If a value out of the setting range of the output range is attempted to be output, an error will occur and error code 191H is
stored in 'Latest error code' (Un\G0); 'Error flag' (Un\G69, b15) turns on at this time. If this error (error code: 191H) occurs
during wave output, the analog output value will be as follows.
• If an attempt is made to output a value below the minimum value of the output range, the analog output value will be the
minimum value of the output range.

If an attempt is made to output a value below the minimum value of the output range, the analog output value will be the minimum value of the output
range.
If an error with error code 191H occurs due to setting a digital input value outside the range, restore the digital input value to
the value within the range before turning offonoff 'Error clear request' (Un\G70, b15).
The buffer memory address to register the wave data being out of range can be examined using the wave output digital value
out-of-range address monitor.
