13-02 Stop Event

Option: Function:

[33] Digital input DI18 Use the value of DI18 in the logic rule

(High = TRUE).

[34] Digital input DI19

[35] Digital input DI27 Use the value of DI27 in the logic rule

(High = TRUE).

[36] Digital input DI29 Use the value of DI29 in the logic rule

(High = TRUE).

[39] Start command This event is TRUE if the frequency

converter is started by any means (either

via digital input, fieldbus or other).

[40] Drive stopped This event is TRUE if the frequency

converter is stopped or coasted by any

means (either via digital input, fieldbus

or other).

[42] Auto reset trip This event is TRUE if the frequency

converter is tripped (but not trip-locked)

and an Automatic Reset is issued.

[50] Comparator 4 Use the result of comparator 4 in the

logic rule.

[51] Comparator 5 Use the result of comparator 5 in the

logic rule.

[60] Logic rule 4 Use the result of logic rule 4 in the logic

rule.

[61] Logic rule 5 Use the result of logic rule 5 in the logic

rule.

[70] SL Time-out 3 Use the result of timer 3 in the logic rule.

[71] SL Time-out 4 Use the result of timer 4 in the logic rule.

[72] SL Time-out 5 Use the result of timer 5 in the logic rule.

[73] SL Time-out 6 Use the result of timer 6 in the logic rule.

[74] SL Time-out 7 Use the result of timer 7 in the logic rule.

[83] Broken belt A broken belt condition has been

detected. This function must be enabled

in 22-60 Broken Belt Function.

13-03 Reset SLC

Option: Function:

[0] * Do not reset

SLC

Retains programmed settings in all group

13 parameters (13-*).

[1] Reset SLC Resets all group 13 parameters (13-*) to

default settings.

3.9.3 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:

Select the variable to be monitored by

the comparator.

[0] * Disabled

[1] Reference

[2] Feedback

[3] Motor speed

[4] Motor current

[6] Motor power

[7] Motor voltage

[12] Analog input AI53

[13] Analog input AI54

[20] Alarm number

[30] Counter A

[31] Counter B

13-11 Comparator Operator

Array [6]

Option: Function:

[0] Less Than (<) Select < [0] for the result of the evaluation

to be TRUE, when the variable selected in

13-10 Comparator Operand is smaller than

the fixed value in 13-12 Comparator Value.

The result will be FALSE, if the variable

selected in 13-10 Comparator Operand is

greater than the fixed value in

13-12 Comparator Value.

[1] * Approx.Equal (~) Select ≈ [1] for the result of the evaluation

to be TRUE, when the variable selected in

13-10 Comparator Operand is approxi-
