PITCH ERROR COMPENSATION FANUC 16/18


Notes on Pitch Error Compensation


  1. The option for pitch error compensation must be enabled

  2. If any of the parameter are changed, you must power down the control. (Parameter 3620, 3621, 3622, 3623 and 3624). See parameter definition on the next page or refer to Parameter Manual.
  3. If any of the compensations values are changed, you only need to reference (HOME) the axis.

  4. If the parameter are setup correctly, the axes designation (X,Y,Z) will appear in the pitch error compensation table.

  5. The number that appears in parameter 3620 will be your first compensation point.

  6. All axes compensation is done from the reference (HOME) position. You must start at HOME position when you compensate an axis.

  7. The 1024 compensation points can be divided up any way necessary to cover all axes. Axes are not limited to any specific number of points.

  8. On a “TT” control each Head has a separate set of compensation parameters and a separate compensation table. Make sure you have selected the correct slide and HEAD combination.
  9. HOME position is actually the beginning of the first compensation interval (Comp. point) as defined by parameter 3620. When you LASER the axis, if you want the first interval of movement from HOME to be compensated, that value must be entered in the compensation table address associated with parameter 3620. How you select parameter 3620 is defined on the next page under PARAMETERS.

  10. Parameter 3621 < or =" parameter" or =" parameter"> parameter 3620.

Direction of Compensation:


  1. Positive going axis: Parameter 3621 < or =" parameter"> parameter 3620. From HOME position the axis count up positive. The axis reference in the negative direction

  2. Negative going axis: Parameter 3621 < or =" parameter"> parameter 3620. From HOME position the axis count up negative. The axis reference in the positive direction

    Note* If you have a negative going axis, your table must have at least one positive compensation point from your reference. If you don’t the axes designation (X,Y,Z) will not appear in your compensation table and pitch error will not work. You do not have to use the one positive compensation point but it must appear in your table. Parameter 3620 can not equal parameter 3622.

FANUC Frequently asked Question (FAQ)

Q: FAPT LADDER: DOS version of the FAPT LADDER in the WIN98 how to install and how to use?

A:

  1. (COPY directly to a computer file on the hard drive, double-click to FLADDER.EXE;
  2. In the config.sys file, adding: device = c: \ windows \ ansi.sys (in your own computer Search to see ansi.sys document in which the directory, wrote on the path)

Q: PMC-SA1 I would like to ask the type of preparation of the ladder in the map FLADDER 111 software SB7
into what types of? (0i MC)

A: Hello, Perform the following steps .

  1. run FANUC "FAPT LADDER_ Ⅲ" programming software
  2. Click [File] Bar, select [Open Program], to open a PC to change the Windows version of the ladder types of documents (PMC-SA1).
  3. Toolbar option [Tool] in the conversion of mnemonic [Mnemonic Convert], showed [Mnemonic Conversion] page. The document Mnemonic (Mnemonic File) column to be among the new documents, including documents path. (Convert Data Conversion of data types (Convert Data Kind) column to be the choice of conversion, generally for ALL.
  4. After the completion of the above options, click [OK] to confirm, and then convert the data show that information, no other errors after the closure of this information page, and then shut down [Mnemonic Conversion] page.
  5. Click [File] Bar, select [New Program], the goal of a new version of Windows ladder at the same time targeting the Windows version of the PC ladder type (PMC-SB7).
  6. Toolbar option [Tool] source in the conversion of [Source Program Convert], showed [Source Program Conversion] page. The document in the middle (Mnemonic File) column generated just need to choose among the documents, including documents path.
  7. After the completion of the above options, click [OK] to confirm, and then display the data conversion information, "All the content of the source program is going to be lost. Do you replace it? ", click [is] confirmed that no error message after the closure of this page, and then shut down [Source Program Conversion] page.  This will complete the next version of Windows on the same Ladder between different types of PC conversion, for example, the PMC_SA1 ladder KT13.LAD converted to PMC_SA3 the MM.LAD ladder, and the conversion of MM.LAD ladder after ladder of Logic KT13.LAD with the same relationship.
