Climatic conditions ServoOne
In transit
As per EN61800-2, IEC60721-3-2 class 2K3
1)
Temperature -25°C to +70°C
Relative atmospheric
humidity
95% at max. +40 °C
In storage
As per EN61800-2, IEC60721-3-1 classes 1K3 and 1K4
2)
Temperature -25°C to +55°C
Relative atmospheric
humidity
5 to 95%
In operation
As per EN61800-2, IEC60721-3-3 class 3K3
3)
Temperature
-10°C to +40°C, up to 55°C with power
reduction (2%per°C)
Relative atmospheric
humidity
5 to 85% without condensation
1) The absolute humidity is limited to max. 60g/m³. This means, at 70°C for example, that the relative atmospheric humidity
may only be max. 40%.
2) The absolute humidity is limited to max. 29g/m³. So the maximum values for temperature and relative atmospheric humidity
stipulated in the table must not occur simultaneously.
3) The absolute humidity is limited to max. 25g/m³. That means that the maximum values for temperature and relative atmos-
pheric humidity stipulated in the table must not occur simultaneously.

A.5 Dynamic temperature monitoring
Should the coolant flow rate collapse or not become established, the power stage could
overheat. For this reason the drive controllers BG5 and BG6a are equipped with dynamic
monitoring of the heat sink temperature and drive controller BG7 is equipped with static
monitoring or the temperature of the power stage; this monitoring shuts down the drive
controller in the event of overtemperature.
Independent of the temperature gradient, the drive controller shuts down at the follow-
ing heat sink temperature:
