P434 Function output 1 (K1)
P
Control terminals 1/2: The settings 3 to 5 and 11 work with 10% hysteresis, i.e. the relay contact
closes (fct. 11 opens) when the limit value is reached and opens (fct. 11 closes) when a 10%
smaller value is undershot. This behaviour can be inverted with a negative value in P435.

0 = No function
open
1 = External brake, to control a mechanical brake on the motor. The
relay switches at a programmed absolute minimum frequency (P505).
For typical brakes a setpoint delay of 0.2 … 0.3 seconds should be
programmed.
A mechanical brake can be directly AC switched. (Please note the
technical specifications of the relay contacts)
Closes
2 = Inverter operating, the closed relay contact indicates voltage FI
output (U - V - W).
Closes
3 = Current limit, based on the setting of the motor rated current in
P203. This value can be adjusted with the standardisation (P435).
Closes
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).
Closes
5 = Frequency limit, based on motor nominal frequency setting in P201.
This value can be adjusted with the standardisation (P435).
Closes
6 = 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 – contact opens.
Closes
7 = Error, general error message, error is active or not yet
acknowledged.
Æ Error – contact opens
(ready – contact closes)
Opens
8 = Warning: general warning, a limit value was reached that could lead
to a later shutdown of the FI.
Opens
9 = Overcurrent warning: At least 130% of the nominal FI current was
supplied for 30 seconds.
Opens
10 = Overtemperature motor (warning): The motor temperature is
evaluated via a digital input. Æ Motor is too hot. Warning occurs after
2 seconds, overheating switch-off after seconds.
Opens
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%.
Opens
12 = Relay via P541 – external control, the relay can be controlled with
parameter P541 (Bit 0) independently of the actual operating status of
the FI.
Closes
13 = Torque limit gen. active Limit value in P112 has been reached in
the generator range. Hysteresis = 10%.
Closes

18 = FI ready: The FI is in operative condition. Following successful
enabling, it will deliver an output signal.
