  • Page 95 Control PCB can cause this fault. Verify all connections and verify that the Drive Control PCB is properly grounded. This fault is usually caused by electrical noise causing the DSD 412 microprocessor to malfunction. If this occurs when the car is stationary, the car controller can quickly reset it.

    DRIVE FAULTS ERROR/FAULT CODE PROBABLE CAUSE/ — CORRECTIVE ACTION F935 Calibration of bus voltage and armature voltage feedback circuits do not match. Probable causes: Missing wire to bus or armature voltage feedback circuits. Component problem - Feedback voltage divider ratios do not match. *may occur during Self-Tune (Fctn #997) or Self-Diagnostic (Fctn #998).

    The Control Display Unit (CDU) function #981 may be used to directly read and track the status of logic input and output signals at DSD 412 drive terminals. This is an easy way to verify the integrity of input and output logic signals to the drive. Refer to specific connection diagrams for your application to confirm the definition of how each signal is being used.
