Identifying Acramatic 950 monitors

Image
  There are 3 basic types of Acramatic 950 OSAs (Operator Station Assembly): RSKI, TSKI, and SSKI. The SSKI's are very rare, and I'm not going to cover them. When you send your OSA in to us to get updated, we like to know what kind of unit we are getting ahead of time so we are prepared. You can tell the difference by looking at the back of the unit where the RED, BLUE, GREEN... bnc cables come into the unit. A TSKI unit only has a single db9 plug there. A RSKI unit will have 4 ports there, however only 2 of them will be used.  The RSKI added the ability the run the analog feedrate and spindle override pots through the monitor instead of an ADC board in the I/O rack. Some divisions of Cincinnati used this functionality. If you are not using the analog pot interface on the side of the RSKI board, a TSKI unit will work fine in your machine. Look at the left hand side of the monitor when viewed from the back. You may have to remove the aluminum cover on the side, and see if any w...

Acramatic 950 software version

Image
  This article covers the method of finding the control software version of your control. The software version can be found on the main blue screen when you first boot the control. It can also be found by pressing "Machine Setup" --> "Access" --> "Service". It will be in yellow letters at the top of the screen. The software version will always follow the format of "X.X mod X"  Example "3.1 mod 5A" "2.0 mod 8"  There are some special cases where custom software has been issued for the control... "2.0 mod 8 Special"      

Acramatic 950 Serial Number

Image
  When trying to order replacement software or options upgrades for the A950 control, we need to know your control serial number. This is rather confusing, as the number we are looking for is referred to as the "serial number", but we really want the Product Number of the control. This is located 2 places... The first is on the Options disk in the blue box of software. The second is on a plate riveted to the lower left hand corner of the A950 card cage. The serial number usually follows a pattern of 51-950-15x-xxxx We want the product number on this plate:

Acramatic 950 Backup procedure

Image
First  - Download the zip file containing the backup that matches the software release for your control from here: Acramatic 950 backup disks YOU MUST REGISTER ON THE FORUM TO BE ABLE TO DOWNLOAD THESE. The archive does contain a file for each disk called "UPDATE.CMD". A lot of virus scans and email systems will complain about this file. It's a completely harmless file and NOT a virus. Extract the zip file. You will have 2 folders. 1 for the Master Save Disk, 1 for the Restore Disk. Copy the files from the Save folder onto a floppy. Don't copy the directory to a floppy. Just the files. Your floppy should have only 2 files on it. UPDATE.CMD and MASTER. Master is a 0 byte file, so don't worry. Copy the 3 files from the Restore folder onto a floppy. Your floppy should only have 3 files. UPDATE.CMD, MASTER, and RESTORE   Second - Insert the floppy into the 950 Turn switch 1 on the BOH board in the card rack on.   If the control is already on, press the reset button on...

Adjusting Servo Gains

   Most of the time after a motor, tach, or drive replacement, the gain will be off. This article will explain the correct way to reset the gain. We are going to assume a gain of 1.00 and this example is based on rel 3.x software. This procedure has worked on every drive/control that I've ever worked on that is analog based.      Cincinnati made it way to easy to adjust the gains from the control using the handy "Increase/Decrease" button. Unfortunately, this changes some numbers that were factory calculated, which affect the analog output to your drive. Basically, we send the drive +/-10vdc to tell it how fast to go. Both the control manufacturers and the drive manufacturers want their products to be universal. We might put a drive on our machine that only accepts +/-5VDC as a command.  By Increasing or Decreasing the gain, we are changing a value on the 950 called "motor rpm/volt". Basically, how fast does our motor turn for 1 volt of command we give...
