Function:
Selectable if 1-90 Motor Thermal
Protection is set to [20] or [21]. If
the alarm 164 ATEX ETR
cur.lim.alarm is active, the output
will be 1.
Selectable if 1-90 Motor Thermal
Protection is set to [20] or [21]. If
the alarm 166 ATEX ETR
freq.lim.alarm is active, the output
will be 1.
Protection is set to [20] or [21] ]. If
the alarm 163 ATEX ETR
cur.lim.warning is active, the
output will be 1.
Selectable if 1-90 Motor Thermal
Protection is set to [20] or [21]. If
the warning 165 ATEX ETR
freq.lim.warning is active, the
output will be 1.
Function:
Retains programmed settings in all
parameter group 13 parameters (13-**).
Resets all parameter group 13 parameters
(13-**) to default settings.

In addition, there are digital values that will be compared
to fixed time values. See explanation in 13-10 Comparator
Operand. Comparators are evaluated once in each scan
interval. Use the result (TRUE or FALSE) directly. All
parameters in this parameter group are array parameters
with index 0 to 5. Select index 0 to programme
Comparator 0, select index 1 to programme Comparator 1,
and so on.

Function:
Choice [1] to [31] are variables which
will be compared based on their values.
Choice [50] to [186] are digital values
(TRUE/FALSE) where the comparison is
based on the amount of time during
which they are set to TRUE or FALSE,
respectively. See 13-11 Comparator
Operator.
Select the variable to be monitored by
the comparator.
[0] DISABLED The comparator is disabled.
