5.3.5 Oil and water cooling
Activation
Oil and water cooling is provided. The function can be activated by means of
configuration:
Table 28: Activation
P-0-1380
Bit 2
FALSE
TRUE
For oil cooling, an on/off valve is controlled by parameter P-0-1418 bit 2 depending
Oil cooling
on the oil temperature.
If the oil temperature (P-0-1279) is above the threshold temperature (P-0-1389 [19])
for a debouncing time (P-0-1389 [24]), cooling is started.
If the oil temperature (P-0-1279) for a debouncing time (P-0-1389 [24]) is lower than
the switch-on threshold by the hysteresis (P-0-1389 [18]), cooling is stopped.

Bit 2
FALSE
TRUE
For water cooling, an on/off valve is controlled by parameter P-0-1418 bit 6
Water cooling
depending on the motor winding temperature.
The valve for water cooling is controlled whenever the valve for oil cooling is
controlled.
In addition, the water valve is controlled if the motor winding temperature
(S-0-0383) is above the threshold temperature (P-0-1389[21]) for a debouncing time
(P-0-1389[24]).
If the motor winding temperature (S-0-0383) for a debouncing time (P-0-1389 [24])
is lower than the switch-on threshold by the hysteresis (P-0-1389 [20]), cooling is
stopped.
