The export of this product is subject to the authorization of the government of the country from where the product is exported. In this manual we have tried as much as possible to describe all the various matters. However, we cannot describe all the matters which must not be done, or which cannot be done, because there are so many possibilities. Therefore, matters which are not especially described as possible in this manual should be regarded as "impossible". SAFETY PRECAUTIONS This section describes the safety precautions related to the use of CNC units. [. . . ] 7 Check the screen for the M, S, T, and B codes to be executed. If they are found, enter the MDI mode, then execute the M, S, T, and B functions. After execution, restore the previous mode. These codes are not displayed on the program restart screen. 8 Check that the distance indicated under DISTANCE TO GO is correct. Also check whether there is the possibility that the tool might hit a workpiece or other objects when it moves to the machining restart position. If such a possibility exists, move the tool manually to a position from which the tool can move to the machining restart position without encountering any obstacles. The tool moves to the machining restart position at the dry run feedrate sequentially along axes in the order specified by parameter settings (No. Machining is then restarted. Explanations D Block number When the CNC is stopped, the number of executed blocks is displayed on the program screen or program restart screen. The operator can specify the number of the block from which the program is to be restarted, by referencing the number displayed. The displayed number indicates the number of the block that was executed most recently. For example, to restart the program from the block at which execution stopped, specify the displayed number, plus one. The number of blocks is counted from the start of machining, assuming one NC line of a CNC program to be one block. < Example 1 > CNC Program O 0001 ; G90 G92 X0 Y0 Z0 ; G01 X100.

D Storing / clearing the block number D Block number when a program is halted or stopped The block number is held in memory while no power is supplied. The number can be cleared by cycle start in the reset state. The program screen usually displays the number of the block currently being executed. When the execution of a block is completed, the CNC is reset, or the program is executed in singleblock stop mode, the program screen displays the number of the program that was executed most recently. When a CNC program is halted or stopped by feed hold, reset, or singleblock stop, the following block numbers are displayed: Feed hold : Block being executed Reset : Block executed most recently Singleblock stop : Block executed most recently For example, when the CNC is reset during the execution of block 10, the displayed block number changes from 10 to 9. When MDI intervention is performed while the program is stopped by singleblock stop, the CNC commands used for intervention are not counted as a block. [. . . ] LED display Description The control circuit is not operating normally. Countermeasure (1) Check the 24VDC control supply voltage. If the voltage is low, increase the voltage to an appropriate level. (2) Check whether a fuse in the servo amplifier unit has blown. [. . . ]
