(5) Fan driver
This circuit drives the ribbon motor cooling fan, “SA Fan”.
When pin N8 (FANCTL) of the FPGA (U5) is set to “Low” level, Q601 turns ON and the “SA
Fan” is driven.
* In power saving mode, +5VIO is not supplied. For details, refer to “2-2-6(1) Power supply
circuit”.
The “SA Fan” is driven according to the temperature of the “SA Ribbon Motor F” that is
detected by the ribbon motor temperature sensor.
When the temperature is under 45
C (113F), the “SA Fan” is not driven.
While the “SA Ribbon Motor F” is running, if the temperature exceeds 45
C (113F) , the “SA
Fan” starts to turn.
If the temperature is 70
C (158F) or more, the “SA Fan” keeps turning until the temperature
falls below 70
C (158F) regardless of the “SA Ribbon Motor F” is running or not.
