Configuring the Outer Control Loop 9-7
If OCL PROP TRIM SELECT (P.813) is enabled, the signal from the trim range block is
passed through another gain block. The gain of this block is proportional to the
absolute value of the speed reference at the output of the speed loop S-curve block.
The gain of this block ranges from 0 at zero speed to unity gain when the reference is
equal to
TOP SPEED (P.011).
You can check the final OCL value through OCL OUTPUT (P.848).
OCL OUTPUT (P.848)
The output of the
outer control loop in
speed units. This is
the
OCL trim that is
applied to the
speed/voltage control
loop.
Parameter Range: n/a
Default Setting: n/a
Parameter Type: Output

OCL PI LEAD FREQ (P.809)
The lead break
frequency of the
proportional integral
(
PI ) block of the outer
control loop.
Parameter Range: 0.00 to 141.37 RAD / S
Default Setting: 1.00 RAD / S
Parameter Type: Tunable
OIM Menu Path(s): Outer Control Loop ( OCL ) - OCL Tuning
If the OCL is configured as a type 1 position regulator, set this equal to 0.00
(proportional only).
OCL PI NEGATIVE LIMIT
(P.811)
The negative limit of
the outer control loop
PI block.
Parameter Range: 0 to 100% of TOP SPEED (P.011)
Default Setting: 100%
Parameter Type: Tunable
OIM Menu Path(s): Outer Control Loop ( OCL ) - OCL Tuning
OCL PI POSITIVE LIMIT (P.810)
The positive limit of
the outer control loop
PI block.
Parameter Range: 0 to 100% of TOP SPEED (P.011)
Default Setting: 100%
Parameter Type: Tunable
