{ 7 }
[-01] = Digital output 1, Digital output 1 of the variable frequency drive
[-02] = Digital output 2, Digital output 2 of the variable frequency drive (only SK 2x0E)
Settings 3 to 5 and 11 operate with a 10% hysteresis, i.e. the output delivers (Funct. 11 does not
deliver) when the limit value 24 V is reached and switches this off again when a 10% lower value is
undershot (Funct. 11 on again).
This behavior can be inverted with a negative value in P435.
Setting/Function

(see also P435)
0 = No function Low
1 = External brake , to control an external 24 V brake relay (max. 20 mA). The
output switches at a programmed absolute minimum frequency (P505).
For typical brakes a setpoint delay of 0.2-0.3 s should be programmed (see
also P107/P114).
SK 2x0E (Size 4) and SK 2x5E: A typical motor brake (105-180-205 V) can be
connected directly via control terminals 79 MB+/80 MB- (chapter 2.4.2.4).
Low
2 =
Inverter is working , the output indicates voltage at the VFD output
(U - V - W)
.
High
3 =
Current limit , based on the setting of the nominal current (P203). This value
can be adjusted via scaling (P435).
High
4 =
Torque current limit , based on motor data settings in P203 and P206.
Signals a corresponding torque load on the motor. This value can be adjusted
via scaling (P435).
High
5 =
Frequency limit , based on nominal frequency setting in P201. This value can
be adjusted via scaling (P435).
High
6 =
Level with setpoint , indicates that the VFD has completed the frequency
increase or decrease. Setpoint frequency = actual frequency! From a
difference of 1 Hz
 Setpoint value not achieved – signal low.
High
7 =
Fault , general fault message, error is active or not yet acknowledged.

Fault
- low (ready - high)
Low
8 =
Warning , general warning, a limit was reached that could lead to a later
shutdown of the VFD.
Low
9 =
Overcurrent warning : At least 130% of the VFD nominal current was
supplied for 30 seconds.
Low
10 =
Mot. overtemp. warning
, "Motor overtemperature warning"
: The motor
temperature is evaluated.

Motor is too hot. The warning is given
immediately, overheating switch-off after 2 seconds.
Low
11 =
Torque current limit,
"Torque current limit/current limit active warning"
: The
limiting value in P112 or P536 has been reached. A negative value in P435
inverts the reaction. Hysteresis = 10%.
Low
12 =
Value of P541,
"Value of P541 - external control
, the output can be controlled
with parameter P541 (Bit 0) independent of the actual operating status of the
VFD.
High
13 =
Torq.curr. limit gen,
"Drive torque current limit active"
: Limit value in P112
has been reached in the generator range. Hysteresis = 10%
High
16 =
Comparison val. AIN1,
SK 2x0E:
Setpoint AIN1 of the VFD is compared with the value in (P435[-01 or -02]).
SK 2x5E: Setpoint AIN1 of 1st I/O extension is compared with value in
(P435[-01])
