Using the SP Ramp Function to Limit the SP Change Rate Section 4-7
Parameters
Operation at Startup If the SP ramp function is enabled when the Controller is turned ON or when
switching from STOP to RUN mode, the process value reaches the set point
using the SP ramp function in the same way as when the set point is changed.
In this case, operation is carried out with the process value treated as the set
point before the change was made. The direction of the SP ramp changes
according to the relationship between the process value and the set point.
Restrictions during
SP Ramp Operation
Execution of auto-tuning starts after the end of the SP ramp.
When control is stopped or an error occurs, the SP ramp function is dis-
abled.
