Pointer Value pointer setting (see Terms and abbreviations on page
109).

81.19 Flow max prot Defines the action to be taken if the flow (signal selected by
parameter 81.18 Flow source sel) remains above the limit
set by parameter 81.20 Flow max level for longer than the
time set by parameter 81.23 Flow ctrl delay.
Not sel Maximum flow protection disabled. 0
Alarm The drive generates alarm MAX FLOW.1
Fault The drive trips on fault MAX FLOW.2
81.20 Flow max level Defines the maximum flow limit. See parameter 81.19 Flow
max prot.

81.21 Flow min prot Defines the action to be taken if the flow (signal selected by
parameter 81.18 Flow source sel) remains below the limit set
by parameter 81.22 Flow min level for longer than the time
set by parameter 81.23 Flow ctrl delay.
See also parameter 81.24 Flow check delay.
Not sel Minimum flow protection disabled. 0
Alarm The drive generates alarm MIN FLOW.1
Fault The drive trips on fault MIN FLOW.2
81.22 Flow min level Defines the minimum flow limit. See parameter 81.21 Flow
min prot.

81.23 Flow ctrl delay Specifies a delay for minimum/maximum flow protection.
See parameters 81.19 Flow max prot and 81.21 Flow min
prot.
0…12600 s Delay for minimum/maximum flow protection. 1 = 1 s
81.24 Flow check delay After starting the drive, defines a period during which the
minimum flow protection is disabled so that normal flow can
be reached.
0…12600 s Start delay for minimum flow protection. 1 = 1 s
81.25 Appl prot ctrl Enables/disables the Application profile protection function,
based on long-term monitoring of an internal signal. If the
selected signal exceeds (and remains above) the
supervision limit longer than the delay set by parameter
81.27 Prof limit dly, the alarm PROFILE HIGH is generated
and 08.21 Pump alarm word bit 6 set to 1.
Not used Application profile protection disabled. 0
PID error Signal 04.04 Process PID err compared to value of
parameter 81.26 Prof limit.
1
PID out Signal 04.05 Process PID out compared to value of
parameter 81.26 Prof limit.
