Parameters
5-40 Function Relay
Array (Relay 1 [0], Relay 2 [1])
Select options to define the function of the relays.
The selection of each mechanical relay is realised in an array
parameter.
Option: Function:
[24] Ready, Voltage Frequency converter is ready for
OK operation and mains voltage is within
specified voltage range.
[25] Reverse Motor runs/is ready to run clockwise
when logic = 0 and counter clockwise
when logic = 1. Output changes as soon
as reversing signal is applied.
[26] Bus OK Active communication (no time-out) via
serial communication port.
[35] External Interlock See digital input.
[36] Control word bit Bit 11 in control word controls relay.

[60] Comparator 0 See parameter group 13-1*. If Comparator
0 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[61] Comparator 1 See parameter group 13-1*. If Comparator
2 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[62] Comparator 2 See parameter group 13-1*. If Comparator
2 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[63] Comparator 3 See parameter group 13-1*. If Comparator
3 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[64] Comparator 4 See parameter group 13-1*. If Comparator
4 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[65] Comparator 5 See parameter group 13-1*. If Comparator
5 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[70] Logic rule 0 See parameter group 13-4*. If Logic Rule
0 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[71] Logic rule 1 See parameter group 13-4*. If Logic Rule
1 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[72] Logic rule 2 See parameter group 13-4*. If Logic Rule
2 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[73] Logic rule 3 See parameter group 13-4*. If Logic Rule
3 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.

Function:
Logic rule 4 See parameter group 13-4*. If Logic Rule
4 is evaluated as TRUE, the output will go
high. Otherwise, it will be low.

SL digital output See 13-52 SL Controller Action. The input
A will go high whenever the Smart Logic
Action [38] Set dig. out. A high is executed.
The input will go low whenever the Smart
Logic Action [32] Set dig. out. A low is
executed.
SL digital output See 13-52 SL Controller Action. The input
B will go high whenever the Smart Logic
Action [39] Set dig. out. Bhigh is executed.
The input will go low whenever the Smart
Logic Action [33] Set dig. out. B low is
executed.
SL digital output See 13-52 SL Controller Action. The input
C will go high whenever the Smart Logic
Action [40] Set dig. out. C high is executed.
The input will go low whenever the Smart
Logic Action [34] Set dig. out. C low is
executed.
SL digital output See 13-52 SL Controller Action. The input
D will go high whenever the Smart Logic
Action [41] Set dig. out. D high is
executed. The input will go low whenever
the Smart Logic Action [35] Set dig. out. D
low is executed.
The output is high when no alarm is
present.
The output is high when the frequency
converter is running counter clockwise
(the logical product of the status bits
'running' AND 'reverse').
The output is high when 3-13 Reference
Site = [2] Local or when 3-13 Reference Site
= [0] Linked to hand auto at the same time
as the LCP is in [Hand on] mode.
The output is high when 3-13 Reference
active Site [1] or Linked to hand/auto [0] while
the LCP is in [Auto on] mode.
The output is high when there is an active
activ Start command (i.e. via digital input bus
connection or [Hand on] or [Auto on], and
no Stop command is active.
