Parameter Group A00: Pid Controller Parameter - EURA DRIVES E800 series Safety Instructions, Installation And Operating Manual

17) Parameter group A00: PID controller parameter

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
FA02
PID feed-back channel
Controller limits
FA03
Upper controller limit (% of set-point)
FA04
Internal set-point value (%)
FA05
Lower controller limit (% of set-point)
If the controller works beyond the limits in FA03 - FA05 inverter will be disabled,
Polarity
FA06
PID controller polarity
Sleep mode
FA07
Automatic sleep mode
FA09
Frequency threshold for sleep mode activation
FA10
Time delay for sleep mode activation (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
If feed back (pressure) falls below the value in (FA05), inverter will restart again, after the delay-time in (FA11) is up
FA18
Variable set-point allowed
If FA18=0: It is not possible, to change the fixed set-point in (FA04) during controller operation
