An electronic motor protective circuit-breaker is integrated in servo F5-S (see Chapt.
6.7.8). A level of 0...100 % of the tripping time is adjustable with Pn.15. On reaching
the adjusted level, the switching condition „OH2-warning" is set (also see „Digital
outputs"). The response to the warning signal is defined with Pn.14.
An electronic motor protective circuit-breaker is integrated in KEB COMBIVERT (see
Chapt. 6.7.8). When the tripping times, defined according to VDE 0660, are exceeded
the switching condition OH2-warning is set (also see „Digital outputs").
Pn.14 Response
0...5 see Pn.3
6 warning signal only
at dig. output
The interior temperature monitoring protects the inverter against malfunctions caused
by too high temperature in the interior of the inverter. Upon exceeding a unit-specific
temperature the interior fan is activated. If after approx. 10 minutes the temperature is
still too high, the switch off time adjusted with Pn.17 is started, the switching condition
„11" OHI-warning is set and the adjusted response to the warning message is executed.
After expiration of the switch-off time (0...120 s) the error E.OHI is triggered (also see
„Digital Outputs").
The response to the warning signal is defined with Pn.16. Depending on the selected
setting an error/status message E.OHI or A.OHI is ouput. After a cooling phase the
inverter status changes from E.OHI to E.nOHI or in case of warning from A.OHI to
A.nOHI and can then be reset.
Pn.16 Response
0...5 as at Pn.3
6 warning signal only

This parameter determines the response to a set selection error. The possible
reactions correspond to the reactions of Pn3. Depending on the selected setting an
error/status message E.Set or A.Set is output.
This parameter determines the response to a software limit switch error. The possible
reactions correspond to the reactions of Pn3. Depending on the selected setting and
the rotation direction an error/status message E.SLF/A.SLF or E.SLr/A.SLr is output.

Protective Functions
Description
see Pn.3
No effect on the drive. Error is being ignored. Switching
condition do.0...7 Value „10" is set.
Description
as at Pn.3
The prewarning changes into an error. The drive remains
in the error status until a reset signal is detected.
No effect on the drive. Error is being ignored. Switching
condition do.0...7 Value „11" is set.
Function disabled; interior temperature is not
evaluated.
