The fault codes of motor controllers may vary depending on the specific controller type and manufacturer. Here are some common examples of motor controller fault codes:
- Encoder Fault: Indicates that the encoder is invalid or damaged, and cannot read the motor position information normally.
- Overcurrent Fault: Indicates that the motor drive current exceeds the maximum allowable value set by the controller.
- Overtemperature Fault: Indicates that the temperature of the motor or controller exceeds the set safe operating range.
- Phase Fault: Refers to a problem with one of the phases driven by the motor, which may be due to incorrect motor wiring or damaged motor coils.
- Low Voltage Fault: Indicates that the power supply voltage is below the minimum operating voltage requirement of the controller.
- Zero Speed Fault: Indicates that the motor speed detection system failed to detect motor motion or the speed is below the set threshold.
- Overspeed Fault: Indicates that the motor’s operating speed exceeds the maximum allowable speed set by the controller.
- Communication Fault: Indicates that the controller is unable to communicate properly with external devices (such as the main controller or upper computer).
These are just some common examples of motor controller fault codes, and the actual situation may vary depending on the controller model and manufacturer.
