OCL REF REGISTER (P.801)
The reference for the outer control loop that is used when OCL REFERENCE SELECT is set to
REGISTER. Typically used in applications where a constant reference is needed.
Parameter Range: -4095 to 4095
Default Setting: 0
Parameter Type: Tuneable
OIM Menu Path(s): Outer Control Loop (OCL) - OCL Configure
Refer also to Parameters: OCL REFERENCE SELECT (P.800)
OCL REF ROUNDING (P.803)
Specifies the amount of reference smoothing (rounding) for the outer control loop. It is set as a
percentage of the OCL REF RAMP TIME. Rounding is performed at the beginning and end of an OCL
reference change.
Parameter Range: 0 to 50%
Default Setting: 0%
Parameter Type: Tuneable
OIM Menu Path(s): Outer Control Loop (OCL) - OCL Tuning
Refer also to Parameters: OCL REF RAMP TIME (P.802), OCL RAMP OUTPUT (P.846),
OCL REFERENCE (P.845)
If OCL REF ROUNDING is set to 0%, the OCL performs a linear ramp function.
If set to 50%, the entire ramp time is smoothed: 50% at the beginning of the reference change and 50%
at the end. If OCL REF RAMP TIME is 0.0 (ramp block bypassed), this parameter has no affect on the
OCL reference signal. See OCL REF RAMP TIME for block diagram.
OCL REFERENCE SELECT (P.800)
Selects the reference for the outer control loop.
If REGISTER is selected, the reference is obtained from the OCL REF REGISTER.
The I/O Expansion Kit must be installed to use ANALOG IN 1 (terminals 50 and 51 on the I/O expansion
board), ANALOG IN 2 (terminals 52 and 53), or FREQUENCY IN (terminal 39, 40, and 41).
A network kit must be installed to select the network input registers (NETW IN REG 1, 2, or 3).
Note that the network input registers are updated only when CONTROL SOURCE (P.000) is set to
NETWORK and the network is active.
Parameter Range: REGISTER, ANALOG IN 1, ANALOG IN 2, FREQUENCY IN,
NETW IN REG 1, NETW IN REG 2, NETW IN REG 3
Default Setting: REGISTER
Parameter Type: Configurable
OIM Menu Path(s): Outer Control Loop (OCL) -OCL Configure
Refer also to Parameters: NETW IN REG 1 (P.905), NETW IN REG 2 (P.906)
NETW IN REG 3 (P.907), OCL REF REGISTER (P.801)
OCL TRIM RANGE (P.812)
The trim range for the outer control loop. This specifies the amount of control the outer control loop OCL
output signal has on the speed/voltage loop reference (or the CML reference when configured as a Type
III Position Regul.). It is set as a percentage of TOP SPEED. See
OCL PI LEAD FREQ for block diagram.
Parameter Range: -100.0% to 100.0%
Default Setting: 0.0%
Parameter Type: Tuneable, Integer input, retentive
OIM Menu Path(s): Outer Control Loop (OCL) - OCL Tuning
Refer also to Parameters: OCL OUTPUT (P.848), OCL PI LEAD FREQ (P.809),
OCL PI NEGATIVE LIMIT (P.811), OCL PI POSITIVE LIMIT (P.810),
OCL PI PROP GAIN (P.808), TOP SPEED (P.011)
