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 24 V
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. 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).
High
2 = Inverter operating, the output indicates voltage at the FI output (U - V - W) . High
3 = Current limit, based on the setting of the motor rated current (P203).
This value can be adjusted with the 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 with the standardisation (P435). High
5 = Frequency limit, based on motor nominal frequency setting in P201.
This value can be adjusted with the scaling (P435).
High
6 = 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 fault message, fault is active or not yet acknowledged. 
Fault - Low (Ready - High)
Low
8 = Warning, general warning, a limit value was reached which 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. The warning is given
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 = Gen. Torque limit, "Generator torque limit active":Limit value in P112
has been reached in the generator range. Hysteresis = 10%.
High
16 = Reference value Ain1,
Setpoint AIN1 of the FI is compared with the value in (P435[-01 or -02]).
High
17 = Reference value Ain2,
Setpoint AIN2 of the FI is compared with the value in (P435[-01 or -02]).
