PROC ERR TOL (2606) Preset Value: 10.0
Range: 0.0 - 100.0%
The band within which the Opto or Relay Output is active (turned ON)
indicating the process is within the desired range.
PROC PROP GAIN (2607) Preset Value: 1.0000
Range: 0.0000 - 9999.9990
Sets the PID loop proportional gain. Determines how much adjustment to
motor speed is due to process error.
PROC INTG GAIN (2608) Preset Value: 0.0000
Range: 0.0000 - 9999.9990
Sets the PID loop Integral gain. Determines how quickly the motor speed is
adjusted to correct long term error.
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 - 9999.9990
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 Profile
Adjust Band (P2612).
PROFILE ADJ BAND (2612) Preset Value: 50.0
Range: 0 - 200.0%
Active when Profile 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 filtering for the PID process output.
PROC OUT OFFSET
(2615) Preset Value: 0.0
Range: -100.0 to +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.
