On the control screen, check Diagnostic Parameters 200 and 204 . A '1' in the OVC bit indicates an overcurrent condition. fanuc 414 servo alarm z axis detect error

The Z-axis servo amplifier (often an Alpha or Alpha i series module) will show a specific alarm code on its 7-segment display, typically 8, 9, or A . Alarm 8: High current on the first axis (L). Alarm 9: High current on the second axis (M). Alarm A: High current on the third axis (N). Primary Causes of Z-Axis Detect Errors When this alarm occurs, the CNC screen displays

The Z-axis is unique because it must constantly fight gravity. Common root causes include: Diagnose a Fanuc High Current Alarm in 10-Steps The Z-axis servo amplifier (often an Alpha or

The on the Z-axis is a high-current detection error within the digital servo system. It signifies that the CNC control has detected abnormal current flow or a hardware fault related to the Z-axis servo amplifier, motor, or cabling. Because the Z-axis often carries the weight of a spindle or heavy tooling, this error can also be triggered by mechanical binding or counterweight failure. Understanding the 414 Alarm Signal

Test patterns are an essential element of any display calibration. ChromaPure includes some basic patterns that can be displayed through the PC's video card, but for a full suite of test patterns you need another source.

Video test pattern generators, such as the Accupel, are probably the best approach, but this is an expensive option outside the reach of most consumers. For most people the best source of video test patterns is on a disc played through a DVD or Blu-ray player.

ChromaPure now offers such a disc that includes all of the basic test patterns necessary for display calibration. The ChromaPure calibration disc offers test patterns for the following tasks:

Each of these test patterns are offered in full fields, 6.5% windows, and 6.5% APL windows.

The Basic Calibration test patterns on this disc include many extra tips and instructions for use. Simply press the Menu button on you Blu-ray player remote while viewing these test patterns for extra help.

In addition to these color calibration test patterns, the disc also includes original patterns for

The test patterns on the disc are arranged in a way that is conducive to the normal workflow ChromaPure users would normally experience. Also, particular care was taken to ensure that the disc is simple and easy to use. To navigate between patterns in a series (such as grayscale), just use the chapter forward button on the disc player's remote control. For navigation aids or text-based explanations for how to use some of the patterns, just press the pop-up menu button on the remote.

1920 x 1080 test patterns on a 25GB Blu-ray disc (region free, will work anywhere in the world).

A downloadable version is available from the links above. You may download the file in either Blu-ray or AVCHD format. Both files are an .iso.

To burn to a disc, only the AVCHD and a DVD burner are required. A Blu-ray burner is not required. (The resolution will still be 1920x1080 HD on DVD).
