5.2.4 coolant temperature and condensation with oil
The flow temperature should be selected depending on the volume flow that the heat
sink temperature is always 10 K below the overtemperature level (OH) at rated opera-
tion. This avoids a sporadic shutdown.
The maximum heat sink temperature can be found in chapter =>
.
NOTICE
Destruction of the drive controller due to short circuit!
►
The user must guarantee that any moisture condensation is avoid-
ed!
5.2.4.1 Avoid moisture condensation
Supply of temper oil
This is possible by using heatings in the cooling circuit for the control of the coolant tem-
perature. The following dew point table is available for this:
The following table shows the coolant inlet temperature as a function of ambient tem-
perature and air humidity.
