Appendix
A.5 Dynamic temperature monitoring
If the coolant flow breaks down or is not generated, the power stage may overheat.
For this reason size 5 and size 6A servo drives feature dynamic monitoring of the heat
sink temperature which shuts down the servo drive in case of overheating. The servo
drive shuts down at the following heat sink temperature regardless of the temperature
gradient:

A.4 Hydrological data of liquid cooling
ATTENTION!
The temperature of the cooling plate must not be more than +10 °C (+50 °F)
below the ambient temperature. Condensation will result in destruction of the
device.
NOTE:
Customers must provide adequate heat dissipation for the cooling medium.
The coolant should be approved by Moog if it deviates from the details below.

Coolant quality
Recommended: Drinking water + corrosion inhibitor
(e.g. ethylene glycol) Not permitted:
Chloride ions (Cl- >100 ppm),
Calcium carbonate (CaCO
3
>160 ppm)
Pollution
The coolant must be as pure as possible so as not to clog
the ducts. At a suspension concentration above 15 mg/dm³
continuous cleaning is recommended.
Coolant temperature
The coolant temperature may be b5 °C and +40 °C
(+41 °F and +104 °F). However, the coolant temperature must
not be more than +10 °C (+50 °F) below the ambient tempera-
ture, so as to prevent condensation on the heat sink.
