278 Parameters
81.32 Pid enable dev Defines the process actual value level at which the Pipefill
function is disabled and normal PID control is enabled. After
the level is reached, the time defined by parameter
81.33 Pid
enb dev dly is allowed to pass before normal PID control is
enabled. PID reference ramps are then observed (if set).
The value is given in percent of the maximum process actual
value.
0.00 … 100.00% Pipefill / PID control breakpoint. 100 = 1%
81.33 Pid enb dev dly Delay for enabling PID control. See parameter 81.32 Pid
enable dev .
0…12600 s PID enable delay. 1 = 1 s
81.34 Pipefill timeout Defines the maximum allowed time for the Pipefill function. If
the target process actual value (parameter
81.32 Pid enable
dev ) is not reached within this time, the action defined by
parameter 81.35 Pipefill flt ctr is taken.
0…12600 s Maximum Pipefill time. 1 = 1 s
81.35 Pipefill flt ctr Defines the action for the Pipefill timeout (parameter 81.34
Pipefill timeout ).
Alarm The drive generates alarm PIPEFILL TIMEOUT . 0
Fault The drive trips on fault PIPEFILL TOUT . 1
Activate PID Normal PID control is enabled. 2

82.01 Pump clean trig Enables the pump cleaning sequence for the drive, and
defines the triggering conditions.
WARNING! Before enabling the pump cleaning
sequence, ensure it can be performed safely with the
connected equipment.
Notes:
• Multiple triggering conditions can exist simultaneously.
• The cleaning sequence observes the speed limits defined
by parameters 20.01 Maximum speed and 20.02
Minimum speed .
• The drive must be started and its run enable signal
present before the cleaning sequence can be started.
