YASNAC 3000G is a low cost, high performance CNC specifically designed for machining centers to direct a three- or four-motion machine tool. It incorporates the latest microelectronics tech- nology in every design feature, which remarkably upgrades the basic functions and offers a wide variety of optional functions. The improved transistorized PWM servos com- bined with the optimum pulse distribution control provides faster and higher accuracy of machining. The totally-enclosed, dustproof enclosure pro- tects all components from the attack by rugged industrial environment. This contributes...

Table 2.1.1 . Tape Format 1. Functions with t are optional. 2. Only the numbers of digits are shown in the above table. Some of them cannot ex- ceed the maximum programmable value. Refer to the description of each item. 3. Least input increment .(0. 01/0. 001 mm) is parameter-switched. 4. Feedrate is d esignated by either mm (inch) per minute or mm (inch) per revolution, which can be switched by G code. (G94, G95) 6. Inch input is available for the control equipped with an optional Inch/Metric selection. Inch/Metric are parameter-switched. 7. Instead of Deep Hole Drilling Depth Q, addresses...

Tape code (EIA or ISO) can be switched by 4. Label Skip function: After switching on the power.supply, or after making RESET op- eration, Label Skip function becomes effec- tive, and LABEL SKIP lamp on the NC op- eration panel lights. In this condition, all tape information is ignored before the first EOB code is.read. When an EOB code is .read, LABEL, SKIP lamp goes out automat- ically, and a...

2.3.2 LEAST INPUT INCREMENT Sequence number is a reference number for the block and does not affect the machining operation and order. Therefore, sequential numbers, dis- continuous numbers, same numbers and no num- use numbers in numerical order. Sequence number is represented by four digits from 0001 to 9999 with the preceding N. The leading zeros can be suppressed. NOTE: When a number of 5 digits or over is given as a sequence number, the latter 4 digits are effective. When the same sequence number used for several blocks is searched, address search stops after reading out the block...

2.3,3 MAXIMUM PROGRAMMABLE VALUE Maximum programmable values of move com- mand are shown below. Table 2.3.3 Maximum Programmable Values In incremental programming, input values and the accumulative value must not exceed the max- imum programmable value. In absolute programming, input values and move amount of each axis specified by the inputs must not exceed the maximum programmable value. Note: The machine may not function properly if a move command over the maximum program- mable value is given. The above maximum pro- grammable values also apply to distance com- mand addresses I, J, K (R,...

In the above case, the feedrate is: Values of F command at linear interpolation represent the tangential feedrate when three axes are simultaneously controlled. In the above case, the feedrate is: Values of F command at linear interpolation represent the tangential feedrate when four axes are simultaneously controlled . • A command "F0" cause data errors and the alarm code "15" will be displayed. • Any minus value should not be specified for F commands. If specified, the machine will The following feed function may be adopted in place of the feed function A described above when • Commanding...

Note: For details of these G codes, refer to 2. 14. 19 Feed Function Designa- Since F code is modal, the code is effective until the next F code is given. However, whenG94/ G95 are switched over, F code must be desig- nated again. After the designation of G95, the feedrate-of- tool per spindle-revolution can be given by 4 digits following F. The command range of the Table 2,5.3.1 F Code (mm/rev-A) However, the programming of feedrate is re- stricted by the spindle speed (S) as shown below. In the above case, the feedrate is: Note- When G94 command is given, feedrate in mm per minute can be...

2.5.5 SUMMARY OF FEED FUNCTION CUTTING FEED In the following operation, the pattern of auto- matic acceleration and deceleration is exponen- Acceleration and deceleration for rapid traverse and for cutting feed are automatically performed without programming. RAPID TRAVERSE AND MANUAL FEED In the following operation, the pattern of auto- matic acceleration and deceleration is linear. • Manual rapid traverse (RAPID) - Manual continuous feeding (.JOG) ■ Manual HANDLE feeding (HANDLE) The miscellaneous function is specified with the address M and two digits. The function of each chine, except...

M02 is used at.the end of program. When given in automatic operation^ mode, this code stops the automatic operation after the commands in the block containing M02 have been completed. Although the control is reset in most cases, the details are determined by the machine. Re- fer to the machine tool builder's manual. M30 is given at the end of tape. .When given in - automatic operation# mode, this code stops the automatic operation after the commands in the block containing M30 have been completed. In addition, in most cases, the-control is reset and rewinds the tape (or memory).' Since the...
