(3) If decimal point specification in (T) is not made, conversion between the specified value
and actual machine travel distance is required. This affects the following programmed
values and parameters:
Speed (feedrate) :
• Interpolation feedrate F specification in program
• Parameter #1101: Maximum manual handle feedrate setting
• Parameter #1102: Maximum interpolation feedrate setting
• Parameters #1104-#1106: Jog feedrate setting
• Parameters #1500, #1700, #1900: Rapid feedrate setting
• Parameters #1504, #1704, #1904: Reference point return approach speed
• Parameters #1505, #1705, #1905: Reference point return creep speed
Acceleration/deceleration:
• Parameters #1475, #1675, #1975: Interpolation feedrate bias setting
• Parameters #1501, #1701, #1901: First stage linear acceleration/deceleration constant
• Parameters #1502, #1702, #1902: Second stage linear acceleration/deceleration constant
Positions:
• Parameters #1122-#1124: Step feed
• Parameter #1125: Reference point position area setting
• Parameters #1550, #1750, #1950: Soft limit boundary value in positive direction
• Parameters #1551, #1751, #1951: Soft limit boundary value in negative direction
(Example) When decimal point movement is used by setting one command pulse
(0.01 mm) two decimal places in movement, all of the programmed values and
parameter setup values described above are affected: each becomes 10 times
the standard setup unit of one command pulse (0.001 mm)( 0.01 mm =10).
0.001 mm
That is, if F12 is programmed in F setting, movement is made at the rate of
120 mm/min.
• If parameter #1102 (maximum interpolation feedrate) is set to 2400, movement is made at
the rate of 24000 mm/min.
• The maximum programmable value _+99999.999 becomes _+999999.99.
For example, X15. is displayed as X15.00 mm;
Y20.5 is displayed as Y20.50 mm; and
Z45 is displayed as Z 0.45 mm.
(4) If memory operation is performed by programming numeric values.having a decimal
point different from the specified one, alarm (No.16: PROG ERROR) occurs.
(Example) When #1005 = 2 (-two decimal places) is set,
The command block G00 X10.00 Y12.34; is executed normally.
The command block G00 X10.000 Y12.340; results in an alarm.
