Description
the pre-PID operation, a normal PID operation starts immediately.
AP1-22 Pre-PID
Delay
AP1-23
Soft Fill Set
In general, a PID operation starts when the feedback volume (controlled
variables) of PID controller exceeds the value set at AP1-23. However, if
AP1-22 (Pre-PID Delay) is set, the feedback after the set time becomes the
default value for the soft fill PID reference, and the inverter starts the soft fill
operation.
When the feedback or the Soft Fill PID Reference exceeds the Soft Fill Set
value, the soft fill operation ends and a normal process PID operation
begins.
AP1-24
Fill Step Set
AP1-25
Fill Step Time
AP1-26
Fill Fdb Diff
The Soft Fill PID Reference increases each time the set time [at AP1-25
(Fill Step Time)] is elapsed, by the amount set at AP1-24 (Fill Step Set).
However, note that if the difference between the Soft Fill PID Reference
value and the feedback value is greater than the value set at AP1-26 (Fill
Fdb Diff value), the Soft Fill PID Reference value does not increase.
When a PID process is performed after the soft fill PID operation, the PID Reference value
becomes the PID-11 PID Ref1 Set value.
