This article will describe how to change the time on a Fanuc CNC control. You can also learn how to recover the home position and optimize the velocities of the servo systems. If you are not familiar with Fanuc CNC controls, this article is for you. It contains important information that can help you to make the most of your Fanuc CNC machine. Listed below are a few tips that you can use to get started:
Altering the clock on a fanuc control
One of the features that you may find interesting on a fanuc control is the clock. If you’re in need of a timer to help you keep track of the hours, you can change this setting on your CNC machine. To alter the clock on a Fanuc control, you first need to be in the MDI mode. In order to do this, you need to have the parameter write enable feature enabled.
Recovery of the home position
If you’re using a FANUC control, you may need to know how to recover the home position. This feature may be lost if you ignore a battery alarm or leave the machine powered off for too long. Fortunately, recovering the home position is simple, and requires no special tools. To recover the home position, simply select the axis, select the Zero Return mode, close all the doors, and press the Cycle Start button. The axis will begin to move slowly toward the mechanical stroke limit stopper. Then, the FANUC control will detect the motor torque when the axis makes contact with the stopper.
Optimum velocities of the servo systems
Optimal velocities of the system’s servo motors are determined by a closed loop structure with position and velocity feedback. The loop is designed to provide extra stiffness and counter high-frequency disturbances. Various types of feedback are used to control the system, and the PID controller is the most common. The three gains of the system are the proportional, integral and derivative.
Fanuc servo systems are highly energy-efficient, using advanced energy-saving technologies. In fact, Fanuc won the MITI Award for Energy-Saving Equipment in 1999. The servo system is equipped with advanced features and technologies, including an integrated testing environment, parameter and data measurement and tuning options, and resonance elimination tuning functions. FANUC servo systems are designed to ensure the maximum performance from spindle motor systems.
The proposed technique was developed to identify and optimize servo system parameters for synchronization. The proposed method was a two-step procedure, first designing velocity loop control parameters, then identifying system constraints. The proposed method can be summarized in Figure 8. After the initial step, data acquisition and system identification, the virtual servo system and feed drive were established. The virtual model was then used to optimize velocity controllers for all five axes.
The proposed model incorporates mathematical relations among variables such as the number of failures, working time, and mean time between failures. The model also realizes homogeneous sampling to guarantee sample integrity. It is superior to the conventional BP and RBF neural networks. It also includes a method for detecting mechanical transmission faults. There are several potential applications for this model.
