625OPERATION MANUAL(NC MONITOR)

BNP-B2288*(ENG)

IntroductionThis 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 manual thoroughly 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

CAUTIONFor items described as "Restrictions" or "Usable State", the instruction manual issued by the 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 the specifications issued by the machine maker. Refer to the Instruction Manual issued by each machine maker for details on each machine 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 before use. Refer to the following documents. MELDAS 625M Operation Manual BNP-B2278 MELDAS 625 Alarm / Parameter Manual BNP-B2279 MELDAS 625M Programming Manual BNP-B2280< Important Usage Notes >In this NC unit, the machining programs, parameters and tool compensation data are saved in the memory (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 be lost under the conditions described below. To prevent data loss, output important programs, parameters, etc., to a serial input/output device and save them. Refer to Section III-8 Maintenance Functions in this manual for information on how 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 setting parameters. (This is not really a data loss, but it is a loss from the standpoint that the original 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.

Precautions for SafetyAlways read the specifications issued by the machine maker, this manual, related manuals 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". DANGER 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 physical damage may occur if handling is mistaken.

WARNING CAUTION

Note that even items ranked as " CAUTION", may lead to major results depending on the situation. In any case, important information that must always be observed is described.

DANGERNot applicable in this manual.

WARNINGNot applicable in this manual.

CAUTION1. Items related to product and manual For items described as "Restrictions" or "Usable State" in this manual, the instruction manual issued by the machine maker takes precedence over this manual. An effort has been made to describe special handling of this machine, but items that are not described must be interpreted as "not possible". This manual is written on the assumption that all option functions are added. Refer to the specifications issued by the machine maker before starting use. Refer to the Instruction Manual issued by each machine maker for details on each machine 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 before use.

CAUTION2. Items related to installation and assembly Ground the signal cables to ensure stable system operation. Also ground the NC unit main frame, power distribution panel and machine to one point, so they all have the same potential. 3. Items related to preparation before use Always set the stored stroke limit. Failure to set this could result in collision with the machine end. Always turn the power OFF before connecting/disconnecting the input/output device cable. Failure to do so could damage the I/O device and NC unit. To prevent influence from data omission and data transformation in the communication circuit, always verify the data after inputting and outputting machining programs. 4. Items related to screen operation If the tool offset and workpiece coordinate system offset are changed during automatic operation (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 during machine operation, pay careful attention to the sequence operation. All of the various data in the NC memory is erased when formatting. Be sure to use the transfer function to transfer all necessary data to another storage device before formatting. All data will be rewritten the same as normal memory operation when the commands are executed during graphic check to change the tool compensation amount, to change 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" commands become a "G00" operation during running. " ; " "EOB" and " % " "EOR" are explanatory notations. The actual codes are "Line feed" 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 machine maker. If a block in the program is set as the operation start position is set from a block in the program 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 before the 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 from the set starting position block without carrying out these operations and commands. (Continued on next page)

CAUTION6. Items related to operation Program so the mirror image function is turned ON/OFF at the mirror image center. The mirror image center will deviate if the function is turned ON/OFF at a position other than the mirror image center. Stay out of the moveable range of the machine during automatic operation. During rotation, keep hands, feet and face away from the spindle. Carry out dry operation before actually machining, and confirm the machining program, tool offset and workpiece coordinate system offset. If the operation start position is set from a block in the program 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 before the 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 from the set starting position block without carrying out these operations. 7. Items related to faults and abnormalities If a BATTERY VOLTAGE DROP alarm is issued, save the machining program, tool data and parameters before replacing the battery. If the axis overruns or emits an abnormal noise, immediately press the emergency stop button and stop the axis. 8. Items related to maintenance Incorrect connections may damage the devices, so connect the cables to the specified connectors. Do not connect or disconnect the connection cables between each unit while the power is ON.
