Depending on the selected setting a status message E.OL or A.OL is output or the
(Pn.8) fault is being ignored.
Pn.8 Response
0...5 see Pn.3
6 warning signal only
at dig. output
This parameter adjusts the response if one of inputs programmed as limit switch is
(Pn.7) triggered. The possible reactions correspond to the reactions of Pn.3 (see left page).
Depending on the selected setting and the rotation direction an error/status message
E.Prr/A.Prr or E.PrF/A.PrF is output.
The overtemperature detection protects the power module against overload. The
temperature, at which the inverter switches off with error message „E.OH" depends
on the power circuit (usually 90°C). After a cooling phase the status changes from
E.OH to E.nOH and can then be reset.
With Pn.11 a level between 0° C up to 90 °C is adjustable, at which the condition OH-
warning is fulfilled. The response to the warning signal is defined with Pn.10.
Pn.10 Response
0...5 see Pn.3
6 warning signal only
at dig. output
The motor temperature detection protects the motor against thermal overload. A
temperature sensor integrated into the motor winding is connected to the terminals
T1/T2 of the inverter power circuit. Upon exceeding a resistance of 1650 Ohm (e.g. a
motor temperature > Level Pn.62) the disconnecting time adjusted with Pn.13 is started,
the switching condition dOH-warning is set and the adjusted response to the warning
signal is carried out. After the expiration of the disconnecting time (Pn.13) the error
E.dOH is triggered.
Depending on the selected setting a error / status message E.dOH or A.dOH is output
and the selected response is activated. If overheat no longer exists, the message
E.ndOH (or A.ndOH) is output. Only then the error can be reset or the automatic
restart can be carried out.
Pn.12 Response
0...5 see Pn.3
6 warning signal only
at dig. output
7 warning signal
disabled
(default)
A special power circuit is necessary for this function. The motor overtemperature
level defines a temperature in the range of 0...200 °C. On exceeding the adjusted
temperature the turn-off time (Pn.13) starts, the switching condition „46" is set and the
response according to Pn.12 is executed. After expiration of the turn-off time the
inverter switches off with the error message E.dOH. The current temperature is indicated
in ru.46.
At a standard power circuit the switching conditions „9" and „46" are set at Pn.12 =
0...6. At Pn.12 = 7 only the switching condition „46" is set. In the motor temperature
display ru.46 only T1-T2 closed or T1-T2 open is displayed.
