DECIMAL POINT PROGRAMMING
Explanations
Examples
Numerical values can be entered with a decimal point. A decimal point can be used when entering a distance, time, or speed. Decimal points can be specified with the following addresses:
X, Y, Z, U, V, W, A, B, C, I, J, K, R, and F.
There are two types of decimal point notation: calculator–type notation and standard notation.
When calculator–type decimal notation is used, a value without decimal point is considered to be specified in millimeters. When standard decimal notation is used, such a value is considered to be specified in least input increments. Select either calculator–type or standard decimal notation by using the DPI bit (bit 0 of parameter 3401).Values can be specified both with and without decimal point in a single program.
Program command

X1000.0
Command value with decimal point

Unit : mm
1000mm
Unit : mm
WARNING
In a single block, specify a G code before entering a value. The position of decimal point may depend on the command.
Examples:
G20; Input in inches
X1.0 G04; X1.0 is considered to be a distance and processed as X10000. This command is equivalent to G04 X10000. The tool dwells for 10 seconds.
G04 X1.0; Equivalent to G04 X1000. The tool dwells for one second.
NOTE
1 Fractions less than the least input increment are truncated.
Examples:
X1.23456; Truncated to X1.234 when the least input increment is 0.001 mm.
Processed as X1.2345 when the least input increment is 0.0001 inch.
2 When more than eight digits are specified, an alarm occurs. If a value is entered with a decimal point, the number of digits is also checked after the value is converted to an integer according to the least input increment.
Examples:
X1.23456789; P/S alarm 003 occurs because more than eight digits are specified.
X123456.7; If the least input increment is 0.001 mm, the value is converted to integer
123456700. Because the integer has more than eight digits, an P/S alarm 003 occurs.

PROGRAMMING
B–64114EN/01
Explanations
●Constant surface speed control command (G96)
G96 (constant surface speed control command) is a modal G code. After a G96 command is specified, the program enters the constant surface speed control mode (G96 mode) and specified S values are assumed as a surface speed. A G96 command must specify the axis along which constant surface speed control is applied. A G97 command cancels the G96 mode.When constant surface speed control is applied, a spindle speed higher than the value specified in G50S_; (maximum spindle speed) is clamped at the maximum spindle speed. When the power is turned on, the maximum spindle speed is not yet set and the speed is not clamped.S (surface speed) commands in the G96 mode are assumed as S
= 0 (the surface speed is 0) until M03 (rotating the spindle in the positive direction) or M04 (rotating the spindle in the negative direction) appears in the program.

Spindle speed (min–1)
The spindle speed (min–1) almost coincides with the surface speed (m/min) at approx. 160 mm (radius).

? 恒表面切削速度控制指 令(G96)
G96(恒表面切削速度控制指令)是模態(tài) G 代碼。在指定 G96 指令后，程序 進(jìn)入恒表面速度控制方式(G96 方式)且以指定 S 值作為表面速度。G96 指 令必須指定恒表面切削速度控制應(yīng)用那個(gè)軸。G97 指令取消 G96 方式。在 用恒表面切削速度控制時(shí)，主軸速度若高于 G50S_；(最大主軸速度)中規(guī) 定的值，就被箝在最大主軸速度。若通電時(shí)尚未指定最大主軸速度，則主 軸速度不被箝制。在 G96 程序段的 S(表面速度)指令被當(dāng)作 S=0(表面速度
是 0)，直到程序中出現(xiàn) M03(主軸正轉(zhuǎn))或 M04(主軸反轉(zhuǎn))。

The CNC calculates the spindle speed which is proportional to the specified surface speed at the position of the programmed coordinate value on the X axis.

NOTE
1 When an alarm is issued in automatic operation, a single
block stop occurs. The spindle overheat alarm is indicated on the CRT screen, and the alarm signal “SPAL” is output (set to 1 for the presence of an alarm). This signal is cleared
by resetting.
2 Even when reset operation is performed after an alarm occurs, the alarm is issued again unless the cause of the alarm is corrected.
3 No check is made during spindle stop state (*SSTP = 0).
4 By setting the parameter (No. 4913), an allowable range of speed fluctuations can be set which suppresses the
occurrence of an alarm. However, an alarm is issued one second later if the actual speed is found to be 0 min–1.
5 The values of p, q, and r specified in the G26 block are set
in the following parameters. If the specification of p, q, or r is omitted, the value set in the corresponding parameter is referenced.

0.1% as the units of the specified q and r values.
B-64114CM/01 編程 9. 主軸速度功能
注
1．在自動(dòng)運(yùn)行中發(fā)出報(bào)警時(shí)，出現(xiàn)單程序段停止。主軸過熱報(bào)警顯 示在 CRT 屏幕上，同時(shí)輸出報(bào)警信號(hào) SPAL(報(bào)警信號(hào)出現(xiàn)時(shí)置為
1)。此信號(hào)由復(fù)位清除。
2．在報(bào)警出現(xiàn)后即使進(jìn)行復(fù)位操作，報(bào)警仍再出現(xiàn)，除非正確地排 除了故障，報(bào)警才清除。
3．在主軸停止?fàn)顟B(tài)不進(jìn)行檢查(*SSTP = 0)。
4．4913 號(hào)參數(shù)可以設(shè)定抑制報(bào)警的速度波動(dòng)允許范圍。但是如果實(shí) 際的主軸速度為 0min-1，則在 1 秒后會(huì)出現(xiàn)報(bào)警。
5．在 G26 程序段中可以指定 p，q 和 r 的值被設(shè)定在下列參數(shù)中。
如果 p，q 或 r 被省略的話，可以參考參數(shù)中的值。
P：參數(shù) 4914
Q：參數(shù) 4911
R：參數(shù) 4912
6．參數(shù) 4900 的第 0 位（FLR）可以用來指定 0.1%為 p 和 q 值的單位。
