  CNC 625 OPERATION MANUAL (NC MONITOR) BNP-B2288*(ENG)    Introduction This manual is referred to when using the NC Monitor of MELDAS 625.NC Monitor has the following functions, which are useable to the test cutting ;  Setting the parameters to set up the machine.  Monitoring and display of servo and spindle states.  Developing ladder circuit with PLC onboard.  Displaying the PLC device data.This manual explains how to operate, run and set up this NC unit. Read this manualthoroughly before using the NC unit. To safely use this NC unit, thoroughly study the Precautions for Safety on the next page before use. Details described in this manual CAUTION For items described as Restrictions or Usable State , the instruction manual issued bythe machine maker takes precedence over this manual.    An effort has been made to note as many special handling methods in this user's manual.Items not described in this manual must be interpreted as not possible .   This manual is written assuming that all optional functions are added. Confirm with thespecifications issued by the machine maker.   Refer to the Instruction Manual issued by each machine maker for details on eachmachine tool.   Some screens and functions may differ depending on the NC system or its version, andsome functions may not be possible. Please confirm the specifications before use.Refer to the following documents.MELDAS 625M Operation Manual ………………………………………… BNP-B2278MELDAS 625 Alarm / Parameter Manual ……………………………… BNP-B2279MELDAS 625M Programming Manual …………………………………… BNP-B2280 In this NC unit, the machining programs, parameters and tool compensation data are saved in thememory (memory elements). This NC unit's memory is backed up by lithium batteries, and under normal conditions will last 6 years from the date of manufacture. However, data contents could belost under the conditions described below.To prevent data loss, output important programs, parameters, etc., to a serial input/output deviceand save them. Refer to Section III -8 Maintenance Functions in this manual for information onhow to do this.Data in the memory can be lost under these kinds of conditions. (1)Incorrect operation Data can be lost if the operator inadvertently changes data while editing a program or settingparameters.(This is not really a data loss, but it is a loss from the standpoint that the srcinal data is gone.)Data can be lost if the operator inadvertently deletes data or initializes NC unit. (2)Battery life expires When the battery life expires and there is not enough voltage to store the data in the memory,data can be lost by turning the power OFF. (3)Faults Data can be lost when faults occur and the control unit must be replaced. < Important Usage Notes >    Precautions for Safety  Always read the specifications issued by the machine maker, this manual, relatedmanuals and attached documents before installation, operation, programming,maintenance or inspection to ensure correct use.Understand this numerical controller, safety items and cautions before using the unit.This manual ranks the safety precautions into Danger , Warning and Caution .When the user may be subject to imminent fatalities or major injuries if handling is mistaken.When the user may be subject to fatalities or major injuries if handling is mistaken.When the user may be subject to bodily injury or when physicaldamage may occur if handling is mistaken.Note that even items ranked as   CAUTION , may lead to major results depending onthe situation. In any case, important information that must always be observed isdescribed. DANGER Not applicable in this manual. WARNING Not applicable in this manual. CAUTION 1. Items related to product and manual  For items described as Restrictions or Usable State in this manual, the instructionmanual issued by the machine maker takes precedence over this manual.    An effort has been made to describe special handling of this machine, but items thatare not described must be interpreted as not possible .   This manual is written on the assumption that all option functions are added. Refer to thespecifications issued by the machine maker before starting use.   Refer to the Instruction Manual issued by each machine maker for details on eachmachine tool.   Some screens and functions may differ depending on the NC system or its version,and some functions may not be possible. Please confirm the specifications beforeuse. DANGERWARNING   CAUTION    CAUTION 2. Items related to installation and assembly Ground the signal cables to ensure stable system operation. Also ground the NC unitmain frame, power distribution panel and machine to one point, so they all have thesame potential. 3. Items related to preparation before use   Always set the stored stroke limit. Failure to set this could result in collision with themachine end. Always turn the power OFF before connecting/disconnecting the input/output devicecable. Failure to do so could damage the I/O device and NC unit.To prevent influence from data omission and data transformation in thecommunication circuit, always verify the data after inputting and outputting machiningprograms.   4. Items related to screen operation  If the tool offset and workpiece coordinate system offset are changed during automaticoperation (including during single block stop), they are validated from the command of the next block or blocks onwards.When forcibly setting (forcibly outputting) data on the I/F diagnosis screen duringmachine operation, pay careful attention to the sequence operation. All of the various data in the NC memory is erased when formatting. Be sure to usethe transfer function to transfer all necessary data to another storage device beforeformatting. All data will be rewritten the same as normal memory operation when the commandsare executed during graphic check to change the tool compensation amount, tochange the parameters with G10, to write the common variables, etc.Do not change setup parameters without prior approval from the machine maker. 5. Items related to programming  Because of key chattering, etc., during editing, NO NOS. FOLLOWING G commandsbecome a G00 operation during running.   ; EOB and % EOR are explanatory notations. The actual codes are Linefeed and % for ISO, and End of block and End of Record for EIA.   Do not change the fixed cycle program without prior approval from the machinemaker.   If a block in the program is set as the operation start position is set from a block in theprogram and the program is started, the program before the set block is not executed.If there are coordinate system shift commands or M, S, T, and B commands beforethe block set as the starting position, carry out the required commands using the MDI,etc. There is a danger of interference with the machine if the operation is started fromthe set starting position block without carrying out these operations and commands.(Continued on next page)
