Control terminals 1/40 (Section 2.7.2): 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 7.7.2).
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 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 = 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 = Error, 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 = Overtemperature motor (warning): The motor temperature is
evaluated.
Motor is too hot. Warning occurs after 2 seconds,
overheating switch-off after seconds.
Low
11 = 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 = Output via P541 – external control, the output can be controlled with
parameter P541 (Bit 0) independently of the actual operating status of
the FI.
High
13 = Torque limit gen. active Limit value in P112 has been reached in the
generator range. Hysteresis = 10%.
High
18 = FI ready: The FI is in standby state. After being enabled it gives an
output signal.
