Precautions
• Based on the digital value on which the shift-and-add is performed, the alert output function, scaling function, and rate
control function are executed.
• When the value obtained by adding 'CH1 Input value shift amount' (Un\G480) to 'CH1 Digital value' (Un\G460) is out of the
digital setting range, a digital value setting range error (error code: 191H) occurs and the corresponding check code is
stored in 'CH1 Setting value check code' (Un\G400).
• The shift function is enabled only for the normal output. When a value other than 0 is set in 'CH1 Input value shift amount'
(Un\G480) while the wave output function is used, an input value shift amount setting error in wave output mode (alarm
code: 0B2H) occurs and 'Alert output signal' (XE) turns on. Although the wave output continues, 'CH1 Input value shift
amount' (Un\G480) is not added to the wave data to be output.
• Even though 0 is set for 'CH1 Input value shift amount' (Un\G480) after an input value shift amount setting error in wave
output mode has occurred, 'Alert output signal' (XE) does not turn off. Turn on and off 'Alert output clear request' (YE) to
turn off 'Alert output signal' (XE). By this operation, 'Alert output signal' (X8) and the ALM LED turn off, and Latest alarm
code is cleared.
