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.
Amp heat, amplifier overheating means the amplifier’s cooling fins are above 100°C, indicating ambient temperature is too high. The manual's first action is: “In case the alarm was detected below 55°C, contact us.”
Overflow, deviation excessive means the difference between command and feedback position exceeded the set parameter limit. The manual's first action is: “The initial set value of basic para. 54 is 10000 (x 100) [pulse…
Resistor heat, braking (DB) resistor overheat means the braking resistor’s heating power exceeded a specified value, possibly due to high braking frequency or voltage issues. The manual's first action is: “use an exte…
Over load, motor overheating means the motor’s torque command exceeded its allowable limit as detected by the amplifier's thermal relay. The manual lists no action for this code.
Cont (control signal) error indicates an issue with the control signal input. The manual lists no action for this code.
Encoder communication error means there’s a failure in serial communication between the encoder and amplifier, possibly due to wiring issues. The manual's first action is: “The serial communication is performed at 4 […
Resistor heat 2 means the regenerative power processing transistor overheated. The manual's first action is: “The ambient temperature of amplifier should be 55°C max. If an alarm appeared before running such as immedi…
Fuse brown indicates the main circuit fuse is blown due to excessive power, and cannot be replaced without contacting support. The manual's first action is: “The main circuit fuse is for preventing the secondary accid…
Data error, memory error means the non-volatile storage memory on the amplifier has been corrupted. The manual's first action is: “Contents of the non-volatile storage memory mounted on the amplifier are destroyed.”
Cont (control signal) error indicates an issue with the control signal input. The manual lists no action for this code.
Encoder trouble indicates a fault with the 16-bit serial encoder attached to the motor. The manual's first action is: “The 16-bit serial encoder attached to the motor may be broken.”
High voltage, overvoltage means the DC intermediate voltage in the amplifier exceeds its upper limit. The manual lists no action for this code.
Low voltage, undervoltage means the supplied voltage to the amplifier is below the minimum required level. The manual lists no action for this code.
Overcurrent, output overcurrent means the amplifier’s output current exceeded its specified limit. The manual's first action is: “The output current from the amplifier to the motor exceeded a specified value.”
System error indicates a general system malfunction. The manual lists no action for this code.
