- Initialization reset method: In general, if a system alarm is caused by an instantaneous fault, the fault can be cleared by hardware reset or switching on the system power supply in sequence. If the system’s working storage area is confused due to power failure, unplugging circuit boards, or battery undervoltage, the system should be initialized and cleared. Before clearing, attention should be paid to making data copy records. If the fault cannot be eliminated after initialization, hardware diagnosis should be carried out.
- Parameter change, program correction method: System parameters are the basis for determining system functions, and incorrect parameter settings may cause system malfunctions or invalid functions. Sometimes, due to user program errors, malfunctions and shutdowns can also occur. The system’s block search function can be used to check and correct all errors to ensure their normal operation.
- Adjustment: Adjustment is a simple and feasible method. Correct system faults by adjusting the potentiometer. During maintenance in a certain factory, the system display screen is chaotic and adjusted to be normal. For example, in a certain factory, the main shaft experienced belt slippage during startup and braking due to the high load torque of the main shaft, while the inclined rise time of the driving device was set too small and adjusted to normal.
