OCL FEEDBACK SELECT (P.804)
Selects the source for the outer control loop (OCL) feedback signal. The I/O Expansion kit must be
installed to use ANALOG IN 1, or ANALOG IN 2. An AutoMax network module must be installed and
CONTROL SOURCE SEL = NETWORK to access Selections 5 to 9.
Parameter Range: NONE, CML FEEDBACK, ANALOG IN 1, ANALOG IN 2
5 = SPEED LOOP OUTPUT,
6 = ANALOG AUTO REFERENCE
7 = NETW IN REG 1 (not available in SW-version 4.1)
8 = NETW IN REG 2 (not available in SW-version 4.1)
9 = NETW IN REG 3 (not available in SW-version 4.1)
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
