7.13.6 Configuring the frequency-based cooling system control
The optional frequency-based cooling system control function lets you con-
trol the fans in a cooling system using the frequency. The device calculates
the fan speed based on the temperature of the top-oil and the load factor.
The device uses the highest speed derived based on the configured depen-
dencies.
You can set the following parameters for this:
▪ Minimum fan operating time after error: Duration for how long the fans are
to continue running if an error occurs in the cooling system control. The
fans run at full power for this duration.
▪ Minimum fan speed
▪ Maximum fan speed
▪ Upper threshold for top-oil temp.
▪ Lower threshold for top-oil temp.
▪ Upper load factor threshold
▪ Lower load factor threshold
