(1) Set point
(2) Feedback value
Example:
suppose parameter 11002
Set point val
of a pump pressure control is 10 bar, 11070
Const pressure thr
is set to 5%, 11074
Const press offset
is set to 4% and 11076
Fluid loss thr
= 1% with 11078
Fluid loss thr time
= 0.6 seconds
This means that to move to the constant pressure condition the feedback must be more than 9.5 bar.
We can consider 2 cases for restarting:
Case 1: the liquid leakage causes the pressure to fall by 0.1 bar per second
In this case the change is lower than the set threshold and to restart the drive the feedback must be less than 9.1
bar due to the settings in parameter 11074
Const press offset
.
Case 2: the liquid leakage causes the pressure to fall by 0.2 bar per second
In this case the change exceeds that set in PAR 11076
Fluid loss thr
(0.1 bar every 0.6 secongs). After 0.6 seconds
(from when the constant pressure threshold is exceeded) the pressure feedback is 9.38 bar, a leakage is detected
and the drive is restarted.

RW FVS
This parameter defines the time for recognising the loss of the feedback signal.
The alarm is only recognised if parameter 11004
Feedback sel
is set to PAR 1600
Analog input 1X mon
and PAR
1650
Analog input 2X mon
.
The drive recognises the alarm if the feedback signal is equal to zero (no signal) for longer than the time set in PAR
11050
Feedback loss time
. If this parameter is set to zero, the alarm is not recognised.

RW FVS
This parameter defines the error level (expressed as a percentage with respect to the set point) for generating the
PID FB loss
alarm.
The alarm is generated when the PID error is higher than the set threshold.
