Table 17: Control signal terminals 10 and 11 (RO1)
The electrical connection specifications for control terminals 10 and 11 are:
•
250 V AC, max. 6 A
•
30 V DC, max. 5 A
We recommend connecting the loads connected to the relay contact as
follows:

Description
0
RUN
Enable (FWD/REV)
Default Setting
1
Ready
Ready for operation. No fault signal
2
Actual value =
Setpoint value
The output frequency (f-Out) / speed is equal to the setpoint value (REF).
3
Error (Fault)
Fault (not ready)
4
f-Out
≧
P-19
The output frequency (f-Out) is greater than or equal to the value set in P-19
(RO1 upper limit).
5
I-Out
≧
P-19
The output current (I-Out) is greater than or equal to the value set in P-19 (RO1
upper limit).
6
f-Out < P-19
The output frequency (f-Out) is less than the value set in P-19 (RO1 upper
limit).
7
I-Out < P-19
The output current (I-Out) is less than the value set in P-19 (RO1 upper limit).
8
Not Enable
No enable signal (FWD/REV)
9
Actual value
≠
Setpoint value
The output frequency (f-Out) / speed is not equal to the setpoint value (REF).
10
AI2 > P-19
The analog signal at control signal terminal 4 (AI2) is greater than the value
set in P-19 (RO1 upper limit).
11
Ready-to-RUN
Ready for operation. The enable signal (ENA) is present and there is no fault
signal present.
Parameter P-19 (RO1 upper limit) contains the limit used in P-18 (4, 5, 6, 7, 10) for relay RO1 (control signal terminal
10/11) or in P-25 (4, 5, 6, 7) for digital output DO (control signal terminal 8).
