If 2 (Stop) is displayed the Start PID command has not been enabled.
If 3 (Alarm) is displayed a drive alarm condition has occurred
If 4 (Wait) is displayed the drive has been disabled because the output speed has fallen below the threshold set in
parameter 11040 Waitspeed. For further details reference should be made to parameter 11044 Restartspeed.
If 5 (Pressureconst) is displayed the drive has been disabled because the feedback is not as far from the set point
as the value set in parameter 11070 Constpressurethr. For further details reference should be made to param-
eters 11070 Constpressurethr, 11074 Constpressoffsetand 11076 Fluidlossthr.

 11020 Proportionalgain % FLOAT 1.00 0.00 10.00 RW FVS
This parameter species the gain associated with proportional control (P).
If the other two gains (I and D) are set to zero, only proportional control is effective. With a PID error equal to 10% of
the full scale value and 11020 Proportionalgain = 1, the speed reference linked to the PID output is equal to 10%
of Fullscalespeed.

 11022 Integralgain sec FLOAT 1.00 0.00 100.00 RW FVS
This parameter species the gain associated with integral control (I). If proportional gain is set to 1 and the PID error
is constant, the output of the integral block is equal to the input (PID error) after reaching the set integral time (pa-
rameter 11022Integralgain).

 11024 Derivativegain sec INT16 0.000 0.000 1.000 RW FVS
This parameter species the gain associated with derivative control (D). With proportional gain set to 1, when the
PID error has a constant variation, the output of the proportional block is equal to the value of the variation after
reaching the set derivative time (parameter 11024 Derivativegain). The derivative part has the effect of increasing
the response speed, but it may lead to over-compensation.
