Preset Output
The preset output function outputs a constant value (preset output value) independently
from the control output value present up to that point when the following conditions
occur.
• When an input burnout occurs during operation in auto mode or cascade mode.
• When a failure occurs in the A/D converter during operation in auto mode or cascade
mode.
• When the operation of the CX2000 is switched from run to stop.
The initial preset output value is set to 0.0%. However, the preset output value can be
set to a value in the range of –5.0 to 105.0% regardless of the high and low limits of the
output limiter.
Note
If you are setting (changing) the preset output value, presume the case when the preset
output is actually used, check the appropriate output value, and set the value. After
confirmation, change the preset output only when it is necessary.
