Control terminals 1/40 (Section 2.8.2): The settings 3 to 5 and 11 work with 10% hysteresis,
i.e. the relay contact closes (function 11 does not deliver) on reaching the limiting value 24V and
switches this off again if a 10% lower value is undershot (function 11 on again).
This behaviour can be inverted with a negative value in P435.

0 = No function Low
1 = External brake, to control an external 24V brake relay (max. 200mA).
The relay switches at a programmed absolute minimum frequency
(P505).
For typical brakes a setpoint delay of 0.2-0.3sec should be
programmed (see also P107/P114).
A typical motor brake (105-180-205V) can be connected directly via
the control terminals 79 MB+/80 MB- (Section 2.8.2).
High
2 = Inverter is working, the output indicates voltage at the FI output
(U - V - W) .
High
3 = Current limit, based on the setting of the motor rated current in (P203).
This value can be adjusted with the standardisation (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 with the standardisation (P435). High
5 = Frequency limit, based on motor nominal frequency setting in P201.
This value can be adjusted with the standardisation (P435).
High
6 = Level with setpoint (Setpoint reached), indicates that the FI 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 error message, error is active or not yet acknowledged.
 Error – Low (Ready – High)
Low
8 = Warning: general warning, a limit value was reached that could lead to
a later shutdown of the FI.
Low
9 = Overcurrent warning: At least 130% of the nominal FI current was
supplied for 30 seconds.
Low
10 = Overtemp. Warn. Motor, "Motor overtemperature warning": The motor
temperature is evaluated.  Motor is too hot. Warning occurs
immediately, overheating switch-off after 2 seconds. Low
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%. 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 FI. High
13 = Torq curr limit gen, "Generator torque limit active":
Limit value in P112 has been reached in the generator range.
Hysteresis = 10%. High
