5. Servo parameters
5.1 Setting parameters (Series 16)
5.1.1 Setting CNC parameters
CNC parameters setting related to High-speed Cutting are explained.
According to the detail, refer to the “FANUC Series 16 / 18 manual”.
(1) Set the following parameter.
• No.1004 (Bit type) B1=1, B0=1 (IS-C : 0.1µm setting).
• No.1816 (Bit axis type) B6=1, B5=1, B4=1. (DMR=111)
• No.1820 (Word axis type) set to CMR.
• No.1825 (Word axis type) set to Position Loop Gain.
(Note) Generally you should set Position Loop Gain to 18000 or 24000 in case of αL9 or αL6 for Piston
Lathe or Lead cutting machine, and set Position Loop Gain to 3000 in the other case not specified
particularly.
• No.7501#6 - #4 (Bit type) set to Interpolated period for G05.
110 : 0.25msec
111 : 0.5msec
011 : 1msec
001 : 2msec
010 : 4msec
• No.7502#0 (Bit axis type) set to 0. (Acceleration/Deceleration is not used during G05 : M-series)
• No.7505#0 (Bit axis type) set to 1 only for High-speed distribution axis.
(Note) In case High-speed distribution, you must set 1 for both CNC side (No.7505#0) and Servo side
(No.2005#4). In 90A7 series, you should set 1 only for CNC side (No.7505#0).
• No.7505#1 (Bit axis type) to magnification for G05 data.
0 : x 1 times (Usual case)
1 : x 10 times (Special case described below)
(Note) In case that the least input increment is 0.0001 deg for a rotary axis and G05 data exceeds 1 word
(32767) at the high speed.
• No.7510 (Word type) set to maximum control axes during G05.
(2) Set the following parameter to allocate each axis
• No.1023 (Word axis type) set to servo axis number.
Note 1) As a High-speed axis or a Learning axis occupies a servo CPU, allocate it an odd number axis (1
st
or
3
rd
or 5
th
axis). The another axis can not be allocated to the even number axis.
However, 90A7 series can assign the normal axes at even number axis together with High-speed or
Learning axis assigned at the odd number axis.
Note 2) When allocating each axis by No.1023, refer to the following samples.
(Example 1) In the following configuration, set 1, 2, -1 and 3 for No.1023.
Axis name Servo axis number
X axis 1
st
axis
Z axis 2
nd
axis
C axis Cs axis (Spindle)
Y axis 3
rd
axis (High-speed axis or Learning axis)
