Parameter Descriptions
There are digital values that are compared to fixed time
values. See the explanation in parameter 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 0–5. Select index 0 to program comparator 0,
3 3
select index 1 to program comparator 1, and so on.

Function:
Options [1] Reference % to [31] Counter B
are variables which are compared based
on their values. Options [50] FALSE to
[186] Drive in auto mode are digital values
(true/false) where the comparison is
based on the amount of time during
which they are set to true or false. See
parameter 13-11 Comparator Operator.
Select the variable to be monitored by
the comparator.
The comparator is disabled.

[38] Actual Position
[50] FALSE Use to enter the fixed value of false in
the comparator.
[51] TRUE Use to enter the fixed value of true in
the comparator.
[52] Control ready The control board receives supply
voltage.
[53] Drive ready The frequency converter is ready for
operation and applies a signal on the
control board.
[54] Running The motor runs.
[55] Reversing The output is active when the frequency
converter runs counterclockwise (the
logical product of the status bits running
AND reverse).
[56] In range The motor runs within the programmed
current and speed ranges set in
parameter 4-50 Warning Current Low to
parameter 4-53 Warning Speed High.
[60] On reference The motor runs on reference.
[61] Below The motor runs at a reference which is
reference, low less than the value in
parameter 4-54 Warning Reference Low.
[62] Above ref, high The motor runs at a reference which
exceeds the value in
parameter 4-55 Warning Reference High.
[65] Torque limit The torque exceeds the value in
parameter 4-16 Torque Limit Motor Mode
or parameter 4-17 Torque Limit Generator
Mode.
[66] Current Limit The motor current exceeds the value in
parameter 4-18 Current Limit.
[67] Out of current The motor current is outside the range
range set in parameter 4-18 Current Limit.
[68] Below I low The motor current is lower than the
value in parameter 4-50 Warning Current
Low.
