(Note 1) A High-speed axis or a Learning axis occupies one Servo CPU, and can not coexist with another
axis.
A High-speed axis or a Learning axis must be allocated to L-axis (odd number axis).
A High-speed axis is the axis supporting High-speed Interface (G05 activates the interface).
• High-speed axis : No.2005 Bit4 (HSPEED) =1 of the axis FS16.
• Learning axis : No.2008 Bit5 (SLEN) =1 of the axis FS16.
♦ There is not the above under-line restriction in 90A7 series. But a Learning axis must be allocated
to L-axis.
(Note 2) The Learning function by digital servo software enables high-precision control for the command
that is given repeatedly at specified intervals. For example, the lead for video cam drum, the
piston or the cam shaft for car engine are usually made with a conventional cam machine using
mechanical way. Learning function enables the customer’s program to replace a conventional
cam machine with a CNC machine.
(Note 3) The parameters described in this manual for High-speed Cutting tools are applied only to a High-
speed axis and Learning axis.
The servo parameters except a High-speed axis are the same as that for general cutting tools.
(This axis is called the normal axis in this manual from now on.)
(Note 4) You can use 9083 or 9087 series in either Series 16B or Series 16C. You should use 90A3 or 90A7
in i-series.
Never use the servo software out of accord with the above table (Table 1-1)
(Note 5) You should choose 90x3 or 90x7 series based on the following criteria.
Lead Cutting Machine or Piston Lathe …………………………………….. 9083 or 90A3
Cam Grinder or Crank Shaft Grinder ………………………………………. 9087 or 90A7
“Ultra high precision velocity feedback function” is available for 9087 or 90A7.
(Note 6) Refer to the following manual for the general servo parameter and adjustment.
• " FANUC AC Servo Amplifier maintenance Manual " : B-65005E etc.
• " FANUC AC Servo Motor α series parameter Manual " : B-65150E etc.
As for specifications and usage of High-speed cycle cutting (G05), refer to the following CNC
manual.
• " FS16/18 Operator's Manual (Tuning) " : B-61804E
• " FS16/18 Maintenance Manual " : B-61805E
(Note 7)
90A7 series has a large difference from the other Learning series.
• This series supports the High-speed interface without High-speed axis setting. (No.2005#4=0).
If you still set a High-speed axis (No.2005#4=1), one axis occupies one Servo CPU as usual.
• You must allocate a Learning axis (No.2008#5=1) to L-axis as usual.
The Learning memory area of 1
st
axis or 3
rd
axis is different from the area of 5
th
axis. Regarding the
detail, refer to 7.2 Learning memory expanded function.
• A Learning axis does not occupy a CPU, so you can allocate the other normal axis to M-axis.
• This series supports the Tandem control. But this function has partially different specification from
the Tandem control in standard servo series because of the premise used together with Learning
control. Regarding the detail, refer to 7.6 Tandem Learning control function.
• This series does not support the Servo trace function. (90A7 series only)
