5. Servo parameters
5.1 Setting parameters (Series 16i)
5.1.1 Setting CNC parameters
CNC parameters setting related to High-speed Cutting are explained.
For the detail, refer to the “FS 16i / 18i / 160is/ 180is model B Parameter 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 * for 90B3 or 90B7 only
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.
(Ref.) The obsolete specification required to set high-speed axis (N2005#4) for High-speed distribution.
But current 90A3, 90A7, 90B3 and 90B7 series don’t require.
• 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.
