申龙电梯故障代码（Shenlong elevator fault code） Code fault description, fault reason, fault countermeasure 1 controller reset fault Controller 5V low power supply voltage or hardware fault Switch the power supply to 5.25V and change the main controller 2 controller power failure Controller power supply 24V or 5V supply Abnormal Switch controller, power supply, check power supply wiring 3 the frequency converter is not ready for the fault Frequency converter is in fault protection state frequency conversion The device parameter is not set properly Check the source of the fault according to the fault indication of the converter Frequency output signal ready parameter settings 4 frequency converter operation trouble The controller outputs an uplink or downlink command Frequency converter without current output Check the inverter port settings enable signal detection Did the receiver not receive the operation command? Five The encoder signals are not fed back Block encoder fault or electrical The machine hasnt turned Encoder damage frequency divider output loss Bad high speed count input interface wiring error Incorrect motor blocking Replace encoder, replace frequency converter, speed feedback, option check Check wiring check whether or not the brake open Six Wrong phase fault of encoder signal A B phase reversal A B is a high-speed counting wiring for P14 port A reverse phase B 8 R2 short connection fault Stop operation feedback signal of frequency converter Still exist Check the inverter parameter settings and check the output point of the inverter No adhesion Ten Communication failure cannot be established Any communication The controller and the controller and the main outbound car The controller cannot establish communication Check serial communication circuit and connector for line break check The communication chip is damaged and the terminal resistor is set to power off Measuring the resistance between CANH and CANL is around 70 11 calling signal board communication fai
