Process PI
[OCL Fdbk Source] — P.290
Selects whether the outer control loop (OCL)
feedback signal is obtained from an I/O
Expansion kit analog input or from an
eight-sample average of the current minor
loop (CML) feedback signal.
Selecting [Cur Lp Fdbk] allows an outer
current loop to be implemented.

[OCL LeadLag Freq] — P.291
Lead/lag low break frequency of the outer
control loop. Sets the lead break frequency if
[OCL LeadLag Type ] is set to Lead/Lag.
Sets the lag break frequency if [OCL
LeadLag Type] is set to Lag/Lead.
Display/Drive Units:
RD/S
Parameter Type:
Tunable
Group
Process PI
Minimum Value:
0.01 rad/sec
Factory Default:
1.00 rad/sec.
Maximum Value
6.98 rad/sec
The OCL lead/lag high break frequency is determined by the settings of this parameter and the [OCL Leadlag Rato]. For example, if the low
break frequency is 0.50 rad/sec and the ratio is 10, the high break frequency is 5.00 rad/sec.
