(b) the use of electrical motors and commonly used diagnostic methods such as checking whether the digital control system has pulsed signal output; checking whether the energy signal is connected; and whether the input/output status of the lcd observation system meets the starting conditions for the axis; the motor of the server with the electromagnetic brakes confirmed that the brakes had been opened; the drive had malfunctioned; the motor of the server had malfunctioned; the motor of the server had failed; and the motor of the server and the balled wires had failed or the key was removed。

The following is a full description of the functional maintenance of the fanuc digital control system:
1. Control trajectory number (co)I don't know
Clusters controlled by cnc to the server axis. Each group is processed with a knife track, and each group can move individually or simultaneously。
2. Controlled axes
Cnc-controlled totals/tracks of entry to the server axis。
3. Connected control axes (sinsultaneously co.)I don't know
Each track is inserted simultaneously into the server axes。
4. Pmc control axisNtrol by pmc)
Controlled by pmc (programmable machine bed controller) to the server axis. The control command is compiled in the pmc program (grade chart) and therefore is not easily modified, so this method is usually used only for moving a fixed amount of input control。
Cf axis control (t series)
In the carbed system, the reverse position (turn angle) control of the main axis is achieved by the powering motors of the service, as is the case with other axes. The axis is plugged in with other inputs to the axis, processing any curve。
6, cs contour controlI don't know
In the carbed system, the control of the turning position of the main axis (turn angle) is not achieved by fanuc's main axis, but by the power motive for the service. The position (angels) of the main axis is detected by a high-resolution encoder installed on the main axis (not the main axis motor), at which point the main axis works as an input to the service axis, moving at a degree/score, which can be plugged in with other input axes to process the contours。
7 rotary axis control
Set the in-to-axis as a turning axle degreesLocation controlI don't know. Turns the angle for a week, and you can set parameters to any value. The fanuc system is usually an input-to-axis other than the basic axis in order to be set as a rotary axis。
Control axis removed (co)I don't know
Specifies that an entry to the server axis is removed from the control of the cnc without a systematic alarm. It is usually used for switch control, which is performed when the machine bed is not rechanneled and removes the switch engine plug。
9. Server off
The pmc signal will cut the power off to the server axis so that it can move freely outside the control hand of the cnc, but the cnc still monitors the actual location of the axis in real time. This function can be used to control the movement of workstations on the cnc bed with a mechanical wheel, or when the workstation is tightened up by a machine。
10, location tracking (follow-up)
If there is a mechanical shift in the workstation when the server closes, stops or serves the alarm, there is an error in the location of the cnc's error repository. The location tracking function is to modify the site position monitored by the cnc controller to make the error in the location error register zero. Of course, implementation location tracking should be based on actual control needs。
11 incremental encoder
A revolving (angular) position measurement element, mounted on an electric motor axis or a roller wire bar, sends an e. G. A spacing pulse indicating a shift. Since there are no zeros on the plate, the location of the machine bed cannot be indicated. The location of the workstation or blade is indicated only after the machine bed has returned to zero and the coordinates of the machine bed have been established at zero. When used, it should be noted that there are two modes of signal output for the incremental encoder: serial and parallel. The cnc module should have a serial and parallel interface with this。
12. Absolute-value encoder
The revolving (angular) position measurement component has the same purpose as the incremental encoder, with the difference that there are absolute zero points on the encoder, which serve as the basis for the calculation of pulses. The values can therefore reflect the actual location of the machine bed in both map transfer and real time. In addition, the location of the post-closure site will not be lost and it will be ready for processing without returning to point zero. As with the incremental encoder, attention should be paid to the serial output and parallel output of pulsed signals in order to match the interface with the cnc module. (the early cnc system has no serial access
13, fsb (fanuc serial service bus)
Fanuc serial server bus
Bus is a high-speed signal transmission bus between the cnc unit and the server amplifier, which uses a cable to transmit a control signal of 4-8 axes and therefore, in order to distinguish the axes, parameters must be set。
14 simple sync control (simple synchro)Nous control
The two-to-axis are active axes and the other are active axes, receiving cnc movement instructions from the active axis and following the active axis movement, thus achieving the simultaneous movement of the two axes. Cnc monitors the movement of the two axes at any time, but does not compensate for the error of both. If the movement of the two axes exceeds the assigned value of the parameter, cnc sends a warning and stops the movement of the axes. This function is used for the two-axis drive of a large workstation。
15, double drive control (tandem control)
For large workstations, two electric motivations can be used when the power of an electric motor is insufficient to drive, which is what this function means. One of the two axes is the active axis and the other the aerodynamic axis. The active axis receives control instructions from the cnc and increases the drive rectangular from the axle。
