Settings 3 to 5 and 11 work with 10% hysteresis, i.e. the relay contact closes (function 11 does not
deliver) on reaching the 24 V limit and switches this off again when the value drops to a value that is
10% lower (function 11 on again).
This behavior can be inverted with a negative value in P435.
Setting/Function
0 = No function
1 = External brake, to control an external 24 V 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).
SK 2x0E (Size 4) and SK 2x5E: A typical motor brake (105-180-205 V) can be
connected directly via control terminals 79 MB+/80 MB- (chapter 2.4.2.4).
2 = VFD is working, the output indicates voltage at the VFD output
3 = Current limit, based on the setting of the rated motor current (P203). This
value can be adjusted via the standardization (P435).
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
via the standardization (P435). This value can be adjusted via the
standardization (P435).
5 = Frequency limit, based on rated motor frequency setting in P201. This value
can be adjusted via the standardization (P435).
6 = Level with setpoint, indicates that the VFD has completed the frequency
increase or decrease. Setpoint frequency = actual frequency! From a
difference of 1Hz
7 = Fault, general error message, error is active or not yet acknowledged.
Fault - low (ready - high)
8 = Warning: general warning, a limit was reached that could lead to a later
shutdown of the VFD.
9 = Overcurrent warning: At least 130% of the nominal VFD current was
supplied for 30 s.
10 = Mot. overtemp. warning, "Motor overtemperature warning": The motor
temperature is evaluated.  Motor is too hot. The warning is given
immediately, overheating switch-off after 2 seconds.
11 = Torque current limit, "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%.
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
VFD.
13 = Torque current limit gen, "Drive torque current limit active": Limit value in
P112 has been reached in the generator range. Hysteresis = 10 %
16 = Comparison val. AIN1,
SK 2x0E:
Setpoint AIN1 of the VFD is compared with the value in (P435[-01 or -02]).
SK 2x5E: Setpoint AIN1 of 1st IO extension is compared with value in
(P435[-01])
