Integrated PID-controller
An integrated PID-controller is available on standard E800 inverters. It is suitable for simple closed loop control
projects.
Controller configuration for set-point and feed-back channel (see graphic on following page)
FA01
PID set-point channel
Selection: 0: internal reference (value in
FA04
)
1: Analogue input AI1
2: Analogue input AI2
Default setting: 0
FA02
PID feed-back channel
Selection: 1: Analogue input AI1
2: Analogue input AI2
Default setting: 1
Controller limits
FA03
Upper controller limit (% of set-point)
Range: 0.0…100.0 %
Default setting: 100.0
FA04
Internal set-point value (%)
Range: 10.0…100.0%
Default setting: 50.0
FA05
Lower controller limit (% of set-point)
Range: 0.0…100.0%
Default setting: 0.0
If the controller works beyond the limits in
FA03
-
FA05
inverter will be disabled,
(nP)
on display
Polarity
FA06
PID controller polarity
Selection: 0: Positive
1: Negative
Default setting: 1
Sleep mode
FA07
Automatic sleep mode
Selection: 0: activated
1: disactivated
Default setting: 1
FA09
Frequency threshold for sleep mode activation
Range: between F112...F111
Default setting: 5.00 Hz
FA10
Time delay for sleep mode activation (sec.)
Range: 0…500 sec.
Default setting: 15 sec.
If the inverter runs for a programmed time, (set by
FA10)
below the minimum frequency, (set by
FA09)
, it will stop and enter in
sleep mode, displayed as
nP
. (feed-back value must stay within programmed limits FA03-FA04).
FA11
Delay-time for restart from sleep mode
Range: 0…3000 sec.
Default setting: 3.0 sec
If feed back (pressure) falls below the value in
(FA05),
inverter will restart again, after the delay-time in
(FA11)
is up
If
FA18=0:
It is not possible, to change the fixed set-point in
(FA04)
during controller operation
FA18
Variable set-point allowed
Selection: 0: deactivated
1: activated
Default setting: 1
