Overtemperature heatsink (OH)
NOTICE
the inverter is not a temperature measuring device!
➢ The detection of the temperature only serves to protect the inverter
and is, depending on the device type and the current measuring
point, subject to varying degrees of tolerance and error.
Depending on the device size, there are only one or more heat sink temperature
values. If an inverter does not support heat sink temperatures 2 or 3, "5000: tem-
perature measurement not supported" is displayed.
Each supported heat sink temperature has its own overtemperature level and its
own error code.

The drive switches off automatically on reaching an unit-dependent maximum heat
sink temperature. The error reaction can be programmed as described above via
the object pn08 E.OH stop mode (immediate switching off, or triggering of FAULT
REACTION ACTIVE).
The length of time required to shutdown the drive depends on many factors: e.g.
the duration of the deceleration ramp and settings in brake handling (co24 brake
control closing delay and co25 brake control closing time).
The maximum time between occurence overtemperature and switch-off modulation
is 2 seconds.
If the time exceeds 2 seconds and the overtemperature error is still present, it will
be switched off with error message 110: ERROR time OH.
If these 2 seconds are too small to ensure a meaningful completion of the machine
cycle, a warning level pn07 OH warning level can be programmed.
