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
Æ
Setpoint value not
achieved – signal Low.
High
7 = Fault , general error message, error is active or not yet acknowledged.
Æ
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 = Mot or overtemp erature warning : The motor temperature is evaluated.
Æ
Motor is too hot. Warning occurs immediately, overheating switch-
off after 2 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 = Value of P541 – external control , the output can be controlled with
parameter P541 (Bit 0) independently of the actual operating status of
the FI. High
13 = Torq ue curr ent limit gen erator /Generator torque limit active :
Limit value in P112 has been reached in the generator range.
Hysteresis = 10%. High

18 = Inverter ready : The FI is in standby state. After being enabled it gives
an output signal.
