    You must use nickel cadmium batteries. Do not use nickel metal hydrides. Do not use lithium. Using the NMh or Li batteries will destroy the charging circuit in the control.

    You can use any NiCd battery as long as you have 3.6V and a minimum of 250mAh. The higher the mAh rating of the battery, the longer the machine can remain powered off without losing parameters. If you are willing to be creative about the mounting, you can use the rechargable batteries for a cordless telephone. Mitsubishi wants a lot of money for replacements. For example, you can use batteries like these with a little creative installation.

    When you get the battery installed, you need to leave the control powered up for at least 24 hours to get the battery charged.

    To re-initialize the machine:

    Initialize the MC-161 card:
    - In the back cabinet, find the MC-161 card on the control.
    - Locate the DIP switches along the edge of the MC-161 card.
    - Starting from the topmost switch, flip the first, third, and fifth switches on.
    - Turn on the main disconnect, then turn on the control for 30 seconds.
    - Power everything off and set all the DIP switches back to the left/off positions,
    - Power up the control again. There may still be alarms because the process is not complete.

    Format the memory and load the canned cycles:
    - Go to the ALARM/DIAG screen and press the soft key for PLC-I/F.
    - At the bottom of the screen in the first three fields, enter 1001 in the DEVICE field, leave DATA empty, and M in MODE and press input.
    - Go to the TOOL/PARAM screen, and press the soft key for BASE2
    - Change fix_P to have a value of 1.
    - Go to PROGRAM/ IN/OUT screen.
    - Press the soft key IN/OUT at the bottom of the screen.
    - Press the soft key for ERASE.
    - In the DATA field, type FORMAT and press input.
    - Press the soft key INPUT.
    - In the #( ) field, enter 4 and press the input key to reload the canned/fixed cycles.
    - Power off the control, then power on again.

    Next, the machine parameters must be loaded. Hopefully, you have these parameters saved to your PC. If you do not have the parameter file, you may have to contact the machien tool builder. Set I/O parameters to transfer machine parameter file:
    - Go to TOOL/PARAM screen
    - Use NEXT soft key twice to show I/O PARAM and press the soft key for it.
    - On the first screen, find DATA IN, DATA OUT, and NC RUNNING. Set them all the same for now. Set DEVICE to 0. Set PORT to 0 if you're using the connector on the back cabinet or set PORT to 1 if using the port on the side of the front console.
    - Press the soft key NEXT to get to page 2/5.
    - There are three fields to enter data. The first is for the DEVICE you are communicating with (in case you want to use different settings for simple transfer and DNC modes), the second field is the parameter #, and the last is the value of the parameter.
    - Set my machines with the following:
    - These settings will run 9600 baud, 7 data bits, even parity, and 2 stop bits.

    Code:
    DEVICE NAME XON
    BAUD RATE 1
    STOP BIT 3
    PARITY EFF 0
    EVEN PARITY 0
    CR. LENGTH 0
    TERM TYPE 0
    TERM CODE1 0
    TERM CODE2 0
    REWIND CODE 0
    HANDSHAKE 3
    DC CODE PARITY 1
    Transfer the parameter file to the machine
    - Get your PC ready to transfer.
    - Go to PROGRAM/IN/OUT and press the soft key IN/OUT.
    - Press the soft key for INPUT.
    - In the # ( ) field, enter 3 and then cursor over to the DATA field. Leave it blank and press the input key. If the PC is ready and the RS-232 cable is correctly wired, the control will be waiting for data.
    - Go back to the PC and initiate the transfer.
    - When all the data is in, press RESET.
    - Power off the control, then power off the main disconnect.
    - Wait about 5 seconds and power the machine back up.

    Dear Caprirs,

    excellent explanation!

    I have Nomura nn-160D Screw type Lathe with Meldas 310LN control.
    But I don't have its parameters neither hard nor soft.

    If you or any one else can provide, it would be great favour.

    Dear Hlabib, what machine do you have?

    Fellows,

    It is about an year ago when I wrote my last post to request dear members of this forum the parameters of machines Nomura NN160D.

    Since then the machines (two) are standing as rock on the floor.

    Please if any one have pdf / hand written / other version of the parameters please share it with me (free or at cost) at: jawadhafeez2000@yahoo.com


    regards

    Jawad
