OCL PI POSITIVE LIMIT (P.810)
Outer Control Loop PI block positive limit. The output of OCL PI block is never above this limit. See OCL
PI LEAD FREQ for the block diagram.
Parameter Range:
0 to 100% of TOP SPEED
Default Setting:
100%
Parameter Type:
Tuneable
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 PROP GAIN (P.808),
OCL RAMP OUTPUT (P.846),
TOP SPEED (P.011)
OCL PI PROP GAIN (P.808)
The proportional gain of the OCL PI block. See OCL PI LEAD FREQ for the block diagram.
Parameter Range:
0.10 to 128.00
Default Setting:
2.00
Parameter Type:
Tuneable

OCL PROP TRIM SELECT (P.813)
Selects whether or not the output of the Outer Control Loop will be scaled by the absolute value of
SPEED RAMP OUTPUT (output of the Speed Loop S-Curve block).
Parameter Range:
1= DISABLE
2= ENABLE
Default Setting:
1
Parameter Type:
Configurable

Additional Parameters
Refer also to Parameters:
OCL PI LEAD FREQ (P.809), TOP SPEED
(P.011)
If OCL PROP TRIM SELECT
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).
OCL REF RAMP TIME (P.802)
The ramp time for the outer control loop reference. Sets the minimum amount of time for the OCL S-
curve output to change from 0 to full scale and vice versa. If set to 0.0, the ramp block is bypassed.
NOTE: If the ramp block is bypassed, rapid speed change can result.
Parameter Range:
0.0 to 300.0 seconds
Default Setting:
10.0 seconds
Parameter Type:
Tuneable
