Process PI
[OCL LeadLag Ratio] — P.292
The ratio between the low break frequency
and high break frequency of outer control
loop lead/lag. The settings of this parameter
and the [OCL LeadLag Freq] determine the
high break frequency.
Refer to the [OCL LeadLag Freq] parameter
and block diagram for additional information.

[OCL LeadLag Type] — P.293
Selects the outer control loop as lead/lag,
lag/lead, or bypassed.
If the OCL is configured as a type 1 position
regulator, this should be set to Bypass. For a
type 2 position regulator, the lead/lag block
can be used if necessary
Refer to the [OCL Lead/Lag Freq] parameter
and block diagram for additional information.
