Cooling fan control (size B and C only)
As default, the drive's cooling fan is controlled by the drive. The fan will remain off until
the heatsink temperature rises above 60°C or the output current rises above 75% of the
drive rating. The fan will then switch on and run at full speed for a minimum of 10s.
