During the operation of the CNC machine tool for turning and milling, there is a malfunction. We can use the following methods to troubleshoot the problem.

1. Initialization reset method: In general, if a system alarm is caused by an instantaneous fault, hardware reset or switching on the system power supply can be used to sequentially diagnose the fault. If the working storage area of the system is in chaos due to power failure, unplugging or unplugging circuit boards, or undervoltage of the battery, the system must be initialized. Before initialization, attention should be paid to copying and recording the data. If the fault cannot be eliminated after initialization, hardware diagnosis should be carried out.

2. Parameter change, program correction method: System parameters are the basis for determining system functions, and incorrect parameter settings may cause system malfunctions or ineffective functions. Sometimes, user program errors can also cause malfunctions and shutdowns. To address this, the system’s block search function can be used to check and correct all errors to ensure their normal operation.

3. Adjustment is a simple and easy method to implement. Correct system faults by adjusting the potentiometer.

When the spindle of a CNC machine tool for turning and milling occurs belt slippage during startup and braking, the reason is that the spindle load torque is large, and the inclined lifting time of the driving device is set too small, which is adjusted to be normal. The servo system consists of two main parts: the driving device and the executing mechanism.
