Setting Output Specifications
Section 4-2
•
Even if the Output ON Scheduling Method is set, the outputs may be ON at
the same time due to the delay in the output device's operation. In this case,
you can prevent the outputs from being ON simultaneously by setting a
delay with the Delay between Outputs parameter. Refer to the following set-
ting examples for details on using the delay.
•
When using both this function and autotuning, always set this function
before performing autotuning. If this function is set after autotuning, control
performance may deteriorate.
•
When using this function, set the following parameters to their default set-
tings: Output Scaling Upper Limit 1 to 4, Output Scaling Lower Limit 1 to 4,
and Decimal Point C1 to C4. If these parameters are not set to their
defaults, the Output ON Scheduling function will not operate properly.
•
This function will also be applied to manual outputs, outputs during errors,
and outputs while stopped, so these outputs may be lower than their set val-
ues.
•
When using the Output ON Scheduling function, all of the Unit's outputs will
operate with the OUT1 control period.
•
ST will be disabled when using the Output ON Scheduling Method.
