6.10.3 13-1* Comparators
Comparators are used for comparing continuous variables
(i.e. output frequency, output current, analog input etc.) to
fixed preset values.

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.
13-10 Comparator Operand
Array [6]
Option: Function:
Choices [1] to [31] are variables which
will be compared based on their
values. Choices [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.

DISABLED The comparator is disabled.
[1] Reference The resulting remote reference (not
local) as a percentage.
[2] Feedback In the unit [RPM] or [Hz]
[3] Motor speed [RPM] or [Hz]
[4] Motor current [A]
13-10 Comparator Operand
Array [6]
Option: Function:
[5] Motor torque [Nm]
[6] Motor power [kW] or [hp]
[7] Motor voltage [V]
[8] DC-link voltage [V]
[9] Motor thermal Expressed as a percentage.
[10] Drive thermal Expressed as a percentage.
[11] Heat sink temp. Expressed as a percentage.
[12] Analog input AI53 Expressed as a percentage.
[13] Analog input AI54 Expressed as a percentage.
[14] Analog input
AIFB10 [V]. AIFB10 is internal 10 V supply.
[15] Analog input
AIS24V [V] Analog input AICCT [17] [°]. AIS24V
is switch mode power supply: SMPS
24V.
[17] Analog input
AICCT [°]. AICCT is control card temperature.
[18] Pulse input FI29 Expressed as a percentage.
[19] Pulse input FI33 Expressed as a percentage.

[30] Counter A Number of counts
[31] Counter B Number of counts
[50] FALSE Enters the fixed value of false in the
comparator.
[51] TRUE Enters 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 supply signal
on the control board.
[54] Running The motor is running.
[55] Reversing The output is high when the
frequency converter is running counter
clockwise (the logical product of the
status bits “running” AND “reverse”)
[56] In range The motor is running within the
programmed current and speed
ranges set in
4-50 Warning Current Low
to 4-53 Warning Speed High .
[60] On reference The motor is running on reference.
