Functional Description
Digital In- and Outputs
ValueFunction
6
PTC-Warning, at tripping of the motor-PTC connected to the terminals OH/OH. After expiration of an adjustable
delay Pn.15 (0...120s) the inverter switches off.
7
Motor protective relay-Warning, if the electronic motor protective switch (Pn.3) is set to warning (=value 1 or 2).
8
Max. constant current (Stall) exceeded (Pn.13. See function „Constant current limit“.
9
Ramp-stop function active (LA-/LD-Stop) , voltage or current at acceleration /deceleration exceeded. See
function „Ramp stop“.
10
DC-Braking active; see function „DC-braking“.
11
Power-Off-Mode active; see function „Power-Off-Mode“
12
Load (ru.7) > than the adjusted load levels 1...4 in LE.8...LE.11. Load level 1 applies to do.1, ...and so on.
13
Active current (ru.10) > than the adjusted active current level 1...4 in LE.16...LE.19. Active current level 1 applies
to do.1, ...and so on.
14
Actual value = setpoint value at constant operation; at ru.0 = nOP, LS, Error or SSF the condition is met.
15
Inverter is in acceleration phase, at ru.0 = FAcc. rAcc and LAS (acceleration stop)
16
Inverter is in deceleration phase, ar ru.0 = Fdec, rdec and LDS (deceleration stop)
17
Clockwise rotation (forward); not at ru.0 = no.P, LS or Error
18
Counter-clockwise rotation (reverse); not at ru.0 = no.P, L or Error
19
Actual direction of rotation = set direction of rotation
20
Actual value (ru.3) > than the adjusted frequency level 1...4 in LE.0...LE.3. Frequency level 1 applies to do.1,
...and so on.
21
Setpoint value (ru.6) > than the adjusted frequency level 1...4 in LE.0...LE.3. Frequency level 1 applies to do.1,
...and so on.
22
Timer from LE.35 has expired. (see function „Timer“)
23
Operating signal; if no error has occurred ru.0 <> error
24
Run signal; when the modulation of the inverter is active
25
Counter A > than the adjusted value in parameter counter A level (LE.41)
26
DC voltage > than the adjusted UZK-level 1...4 in ...LE.27. UZK-level 1 applies to do.1,...and so on.
27
Low Speed (ru.0=LS) or (Factual=Fset and load (ru.7) in the load window); the load window is defined as follows:

1 (do.1)

28
Cable breakage at 4...20mA setpoint value setting; the condition is met when the setpoint current drops below
2mA
29
±REF at output of characteristic amplifier > percent level 1...4 (LE.62...LE.65); without sign evaluation
30
REF at output of characteristic amplifier > percent level 1...4 (LE.62...LE.65); without sign evaluation
31
Analog option at output of characteristic amplifier > percent level 1...4 (LE.62...LE.65); without sign evaluation;
percent level 1 applies to do.1, ...and so on
32
±REF at output of characteristic amplifier > percent level 1...4 (LE.62...LE.65); with sign evaluation
33
REF at ouput of characteristic amplifier > percent level 1...4 (LE.62...LE.65); with sign evaluation
34
Analog option at output of characteristic amplifier > percent level 1...4 (LE.62...LE.65); with sign evaluation;
percent value 1 applies to do.1, ...and so on
35
Combination condition; Error of OL-Warning or OH-Warning or (status POFF or PLS) and Fout=oHz)
36
System deviation between set and reaL value at regulated operation > frequency level (LE.0...LE.3)
37
Brake control; trips, when the brake is opening (see Chapter 6.9.6)
The hysteresis at value 29...34 depends on LE.69.
At value 29...31 no negative percentage levels may be adjusted, since then the condition is constantly met!
LE.36 adjust the hysteresis for frequency dependend switch (e.g. constant running; switch conditions depends on real or
set value frequency and trigger frequency for DC-Braking)
