SiBE041434E CheckService Diagnosis 985.2 Fan Motor Connector Output CheckCheck No.02 35/42/50 class1. Check the connection of connector.2. Check the motor power supply voltage output (pins 4 - 7).3. Check the motor control voltage (pins 4 - 3).4. Check the rotation command voltage (pins 4 - 2).5. Check the rotation pulse (pins 4 - 1).Check No.03 20/25 class Fan motor wire breakdown / short circuit check1. Check the connector for connection.2. Turn the power off.3. Check if each resistance at the phases U - V and V - W is 90 Ω ~ 100 Ω (between the pins12 - 9, and between 9 - 6). Motor control voltage check1. Check the connector for connection.2. Check the motor control voltage is generated (between the pins 2 - 3). Rotation pulse check1. Check the connector for connection.2. Turn the power on and stop the operation.3. Check if the Hall IC generates the rotation pulse 4 times when the fan motor is manuallyrotated once (between the pins 1 - 3).7654321S1(R19654)Motor power supply voltage (310 ~ 340 VDC)UnusedUnusedGNDMotor control voltage (15 VDC)Rotation command voltage (1~ 6.5 VDC)Rotation pulse input(R11979)121110987654321Phase UFree pinFree pinFree pinFree pinFree pinFree pinPhase VPhase WGNDMotor control voltage (15 VDC)Rotation pulse (5 VDC)S200
