2. CONTROLLED AXES

Item 0i–TC
Number of basic controlled axes 2 axes
Controlled axis expansion (total) Max. 4 axes (Included in Cs axis)
Number of basic simultaneously
controlled axes
2 axes
Simultaneously controlled axis expansion
(total)
Max. 4 axes
NOTE
The number of simultaneously controllable axes for manual
operation (jog feed, incremental feed, or manual handle
feed) is 1 or 3 (1 when bit 0 (JAX) of parameter 1002 is set
to 0 and 3 when it is set to 1).
The names of two basic axes are always X and Z; the names of additional
axes can be optionally selected below by using parameter No.1020.
D G code system A: Y, A, B, and C
D G code system B/C: Y, U, V, W, A, B, and C
Each axis name is determined according to parameter No. 1020. If the
parameter specifies 0 or anything other than the nine letters, the axis name
defaults to a number from 1 to 4.
When a default axis name (1 to 4) is used, the system cannot operate in
MEM or MDI mode.
If the parameter specifies an axis name more than once, only the first axis
to be assigned that axis name becomes operable.
NOTE
1 When G code system A is used, the letters U, V, and W
cannot be used as an axis name (hence, the maximum of
six controlled axes), because these letters are used as
incremental commands for X, Y, and Z. To use the letters
U, V, and W as axis names, the G code system must be B
or C. Likewise, letter H is used as an incremental command
for C, thus incremental commands cannot be used if A or B
is used as an axis name.
2 In G76 (multiple–thread cutting), the A address in a block
specifies the tool nose angle instead of a command for axis
A.
If C or A is used as an axis name, C or A cannot be used as
an angle command for a straight line in chamfering or direct
drawing dimension programming. Therefore, “,C” and “,A”
should be used according to bit 4 (CCR) of parameter No.
