Internal cooling circuit

Specifications
Temperature limits
Ambient temperature:
See chapter
.
Minimum coolant inlet temperature:
Condensation is not allowed. The minimum
coolant temperature to avoid condensation (at an atmospheric pressure of 1 bar) is
shown below as a function of the relative humidity (
φ
) and the ambient
temperature (
T
air
).
Maximum coolant inlet temperature for the drive
Drive with the optional liquid cooling unit (+C140 or +C141):
• 38 °C when the drive output capacity is not derated
• 38 °C … 45 °C when the drive output capacity is derated by 1% per 1 °C
temperature increase.
Drive without the optional liquid cooling unit:
• 42 °C when the drive output capacity is not derated
• 42 °C … 48 °C when the drive output capacity is derated by 1% per 1 °C
temperature increase.
Maximum inlet temperature variation:
±4°C
Maximum temperature rise:
13 °C; depends on mass flow.
Pressure limits
Base pressure:
100…150 kPa (recommended); 200 kPa (maximum). “Base
pressure” denotes the pressure of the system compared with the atmospheric
pressure when the cooling circuit is filled with coolant.

Not allowed as standard but the coolant temperature must be 5 °C or
above. Consult an ABB representative if operation below coolant
temperature 5 °C is required.
Example:
At an air temperature of 45 °C and relative humidity of 65% the coolant
temperature may not be below +36.8 °C
