7.3.17 Switching Conditions (do.00...do.07)
From the following switching conditions one can select up to 8 for further processing. The values are then
entered in the parameters do.00...do.07.

Function Description
0 always switched-off Switching condition never fullled
1 Always active Switching condition always fullled
2 Run signal
Drive is running and there is no malfunction (also set if modulation generally
released, but temporary blocked by for example "motor de-excitation").
3 Ready for operation Drive is ready for operation (inverter state unequal to error).
4 Error There is an error message (inverter state equal to error).
5 Error without auto reset Is not set for errors for which an automatic restart is programmed.
7 Alert signal overload
ru.39 is an overload counter, counting in steps of 1%. On reaching 100 % the
inverter switches off. Upon exceeding of level Pn.09 (default 80 %) the over-
load warning is given. The performance in case of a warning can be adjusted
with Pn.08 (response to OL-warning).

Pre-warning power modules
overheating
Overheating-prewarning (OH)! Depending on the power circuit the inverter
switches off between 60...95°C heat sink temperature. The prewarning is
output, when the level OH-warning (Pn.11) is reached (default 70 °C). The
behaviour in case of an warning can be adjusted with Pn.10 (response to
OH-warning).
9 Pre-warning motor overheating
PTC-prewarning (dOH), on tripping of the motor-PTC connected to the termi-
nals T1/T2. After expiration of an adjustable switch-off time Pn.13 (0...120s)
the inverter switches off with E.dOH. The behaviour in case of a warning can
be adjusted with Pn.12 (response to dOH-warning).
10 Motor protection relay function
F5-M and F5-H (asynchronous motors):
The dened motor protection release time according VDE is up. The beha-
viour on the release of the electronic motor protection relay can be adjusted
with Pn.14 (warning OH2 stop. mode).
F5-S and F5-E (synchronous motors):
The overload counter of the motor protection function for servo motors has
exceeded the value of Pn.15 „OH2 warning level“. If the counter reaches
100%, the error is released. The response to this pre-warning can be adju-
sted with Pn.14 (warning OH2 stop. mode).
11 Warning internal overheating
Interior temperature-prewarning (OHI) is output if the interior temperature of
the inverter exceeds the level OHI-warning. The behaviour can be adjusted
with Pn.16 Pn.16 (response to OHI-warning). An error is generally released
after expiration of the OHI-delay time (Pn.17). Not at Pn.16 = „7“
12 Cable breakage 4...20mA AN1
Cable breakage at 4...20mA setpoint setting at An.01 or An.02. Trips, if the
setpoint current drops below 2mA.
13 Cable breakage 4...20mA AN2
14 Current limit ( I > Pn.20 )
Pn.20 „current limit level“ exceeded (only for v/f characteristic open-loop
operation).
15 Ramp stop active
Ramp is stopped (LA-/LD-Stop active). Pn.24 „LAD load level“ or Pn.25 „LD
voltage“ exceeded at acceleration/deceleration.
16 DC-braking active DC braking active
17 Power off function active The state of the inverter is „Power off function active“.
