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.
