Settings 3 to 5 and 11 work with a 10% hysteresis, i.e. the output delivers (function 11 does not deliver)
when the 24V limit value is reached and switches off again when the value drops to a value that is 10
% less again (function 11 on again).
This behaviour can be inverted with a negative value in P435.
Setting / Function
0 = No function
1 = External brake, to control an external 24V brake relay (max. 20 mA). The
output switches at a programmed absolute minimum frequency (P505).
For typical brakes a setpoint delay of 0.2-0.3s should be programmed (see
also P107/P114).
SK 2x0E (Size 4) and SK 2x5E: A typical motor brake (105-180-205V) can be
connected directly via control terminals 79 MB+/80 MB- (chapter 2.4.2.4).
2 = Inverter operating, the output indicates voltage at the FI output
3 = Current limit, based on the setting of the motor rated current (P203). This
value can be adjusted via the standardisation (P435).
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 the standardisation (P435).
5 = Frequency limit, based on motor nominal frequency setting in P201. This
value can be adjusted via the standardisation (P435).
6 = Setpoint reached, indicates that the FI has completed the frequency increase
or decrease. Setpoint frequency = actual frequency! From a difference of 1 Hz

7 = Error, general error message, error is active or not yet acknowledged.
Fault - Low (Ready - High)
8 = Warning: general warning, a limit value was reached that could lead to a later
shutdown of the FI.
9 = Overcurrent warning: At least 130 % of the nominal FI current was supplied
for 30 s.
10 = Overtemp. Warn. Motor, "Motor overtemperature warning": The motor
temperature is evaluated. Motor is too hot. The warning is given
immediately, overheating switch-off after 2 seconds.
11 = Torque curr. lim. active, "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 %.
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
FI.
13 = Gen. torque current limit, "Drive torque current limit active": Limit value in
P112 has been reached in the generator range. Hysteresis = 10 %.
16 = Reference value Ain1,
SK 2x0E:
Setpoint AIN1 of the FI is compared with the value in (P435[-01 or -02]).
SK 2x5E: Setpoint AIN1 of 1st IO extension is compared with value in
(P435[-01])
