OCL FEEDBACK SELECT (P.804)
Selects the source for the outer control loop (OCL) feedback signal. . To enable the OCL, either the I/O
Expansion kit must be installed, to use ANALOG IN 1, ANALOG IN 2, or a network kit must be installed
to access selections 5 to 9. CONTROL SOURCE SEL (P.000) must be set to NETWORK, or DIG IN 0
SELECT (P.428) must set to OCL ENABLE and parameter OCL ENABLE (P.849) must be ON.
Parameter Range: NONE,
CML FEEDBACK,
ANALOG IN 1, ANALOG IN 2 (Feedback is from I/O Expansion kit analog input)
5 = SPEED LOOP OUTPUT (Feedback is SPD LOOP OUTPUT (P.299) value)
6 = ANALOG AUTO REFERENCE (Fdb. is AUTO REFERENCE (P.188) value)
7 = NETW IN REG 1
8 = NETW IN REG 2
(Feedback is the associated network input register)
9 = NETW IN REG 3
Default Setting: NONE
Parameter Type: Enumerated input, configurable, retentive
OIM Menu Path(s): Outer Control Loop (OCL) - OCL Configure
Refer also to Parameters: CML FEEDBACK (P.397)
OCL LEADLAG LOW FREQ (P.806)
Lead/lag low break frequency of the outer control loop. Sets the lead break frequency if OCL LEADLAG
SELECT (P.807) is set to LEAD/LAG. Sets the lag break frequency if P.807 is set to LAG/LEAD.
Parameter Range: 0.01 to 34.90 RAD/S
Default Setting: 1.00 RAD/S
Parameter Type: Tuneable
OIM Menu Path(s): Outer Control Loop (OCL) - OCL Tuning
Refer also to Parameters: OCL LEADLAG RATIO (P.807)
OCL LEADLAG SELECT (P.805)
The OCL lead/lag high break frequency is determined by the settings of this parameter and the OCL
LEADLAG RATIO. For example, if the low break frequency is 0.50 rad/s and the ratio is 10, the high
break frequency is 5.00 rad/s.

OCL LEADLAG RATIO (P.807)
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 LOW FREQ determine the high break frequency.
See OCL LEADLAG LOW FREQ for discussion and block diagram.
Parameter Range: 2 to 20
