Error, fault and alarm codes of products - what each code means, its causes and what to do - read from the manufacturers’ manuals, with the manual page each answer comes from.
All 5 error codes of the KT KT‑LCD 7 e-bike special meter with their meaning, causes and what to do, taken from the manufacturer's manual with page references.
One and the same signal is allocated to several control input signal (CONTn) terminals on CN1 of amplifier. The manual lists no action for this code.
Absolute value data of the 16-bit serial encoder built in GYC/GYS type motor are lost, detected only when ABS (absolute system) is selected by setting of system para. 99. The manual's first action is: “This alarm is d…
Terminal error occurs when there is a problem with the terminal connections or signals. The manual lists no action for this code.
Absolute data overflow means the absolute position data has exceeded its storage capacity. The manual lists no action for this code.
Absolute data lost indicates that absolute position data has been lost. The manual lists no action for this code.
Encoder heat, encoder overheating occurs when the temperature of the 16-bit serial encoder exceeds a specified value. The manual's first action is: “The ambient temperature for the motor should be 40°C max. If an alar…
The amplifier is overheating with cooling fins above 100°C, requiring ambient temperature control below +55°C or contacting support if detected under normal conditions. The manual's first action is: “In case the alarm…
The deviation between command and feedback positions has exceeded the set value for basic parameter 54, indicating excessive positional error. The manual's first action is: “The initial set value of basic para. 54 is …
The braking resistor in the amplifier is overheating due to excessive heating power, suggesting use of an external resistor or adjustment of acceleration/deceleration times. The manual's first action is: “use an exter…
The motor is overheating because the torque command value has exceeded its allowed limit as detected by an electronic thermal relay. The manual lists no action for this code.
Communication between the 16-bit serial encoder and amplifier is failing, likely due to wiring issues or improper connections. The manual's first action is: “The serial communication is performed at 4 [Mbps] of data r…
The regenerative power processing transistor in the amplifier has overheated due to resistor heat 2. The manual's first action is: “The ambient temperature of amplifier should be 55°C max. If an alarm appeared before …
There is a combination error, possibly from a control signal issue, requiring further investigation. The manual lists no action for this code.
A main circuit fuse in the amplifier has blown due to voltage exceeding 2 [kV], and replacement is not permitted without contacting support. The manual's first action is: “The main circuit fuse is for preventing the s…
