PROC INTG CLAMP
(2609)
Preset Value: 100.0
Range: 0.0 - 100.0%
Sets the level of the Integrator clamp as a percentage of maximum motor
speed.
PROC DIFF GAIN
(2610)
Preset Value: 0.0000
Range: 0.0000 - 1000.0000
Sets the PID loop differential gain. This determines how much adjustment to
motor speed is made for transient error.
PROFILE ADJUST
(2611)
Preset Value: 0
Range: 0 - 1
Off (0)
No adjustment is made.
On (1)
ACC/DEC group is selected based upon comparing process error to Profi le
Adjust Band (P2612).
PROFILE ADJ BAND
(2612)
Preset Value: 50.0
Range: 0 - 200.0%
Active when Profi le Adjust (P2611) is ON. If process error is within this band,
ACC/DEC Group 1 is used. If process error is outside this band, ACC/DEC 2
is used. Useful when the PID’s response needs to differ when process error
is small as compared to when it is large.
PROC SLEEP BAND
(2613)
Preset Value: 0.0
Range: 0 - 100.0%
Non-zero - Enables process PID sleep mode. When Process error remains
within this band for 5 seconds, sleep mode is active (control is disabled,
motor coasts). If at any time the process error moves out of this band, sleep
mode is terminated and normal PID operation is resumed.
Zero - Disables sleep mode.
PROC OUT FILTER
(2614)
Preset Value: 0.00
Range: 0.0 - 100.0 seconds
Sets the amount of fi ltering for the PID process output.
PROC OUT OFFSET
(2615)
Preset Value: 0.0
Range: -100.0 - 100.0%
Sets the amount of offset for the PID process output.
PROC OUT GAIN
(2616)
Preset Value: 100.0
Range: 0.0 - 200.0%
Sets the amount of gain for the PID process output.
SKIP
FREQU-
ENCY
SKIP FREQ 1
(2701)
SKIP FREQ 2
(2703)
SKIP FREQ 3
(2705)
Preset Value: 0 RPM
Range: 0 - 2500
Sets the center frequency on the band to skip or treat as a deadband. Three
bands can be defi ned independently or the three values can be seleted to
skip one wide band.
SKIP BAND 1
(2702)
SKIP BAND 2
(2704)
SKIP BAND 3
(2706)
Preset Value: 0 RPM
Range: 0 - 2500
Sets the span of the band centered on the Skip Frequency. Example: If “Skip
Freq 1” (P2701) is set to 20 RPM and the “Skip Band 1” (P2702) is set to 5
RPM, continuous operation is not in the deadband of 15 to 20 RPM.
AUTO TUNE
ANA OFFSET TRIM
(2901)
Preset Value: 0
Range: 0 - 1
No (0)
No action.
Yes (1)
Measures analog offset for all analog inputs. Set analog inputs to zero
before executing.
