6.11. Solenoid Driver Section
The solenoid drive circuit controls Regist Clutch ,Pickup Solenoid, FTR Solenoid, ADU Solenoid, and PCK Solenoid.
These solenoid and clutch are designed to be driven 24V.
24V power supply (SOLPWR_F) for solenoid driving is controlled by IC600, and power is supplied when D11 (PB0_SOLPWR) is in
High Level. The diodes protect transistors from reverse generated voltage when solenoids are turned off.
NSOLERR is an abnormal detection signal, and the low level signal is input to B10 of IC600 when either clutch or solenoid is
shorted.
