Example Program The following program shows the effect of changing the interpolation accelera-
tion time during interpolation.
: :
N009 G01 X200 Y300
N010 G69 #3/X100
N011 G01 X300 Y500
N012 G01 X500 Y800
: :
The new interpolation acceleration time
is effective between the next two G01
functions after the G69 function.
5-5-21 G70: UNCONDITIONAL JUMP
Unconditionally jumps to the specified block.
Format G70_<jump destination block number> [/L<number of loops>]
Parameters The following table shows the possible settings for the parameters.
Parameter Possible settings
Destination block number N000 to N999
Number of loops 1 to 39,999,999
(E00 to E31)
A0000 to A1999
Description This function unconditionally jumps to the specified block. A fixed number of
jumps (a loop) can be created by specifying a number of loops.
When a number of loops is specified, the destination block number must be
before the current block number.
If another UNCONDITIONAL JUMP function (G70) or a CONDITIONAL JUMP
function (G71) is used to exit a loop before the number of loops has counted
down to zero, the number of loops will be cleared when another loop is started.
A second loop function can’t be executed while a loop is in progress. The follow-
ing diagram demonstrates this programming mistake.

Loops can’t be nested as shown above, but up to 6 loops can be nested by call-
ing subprograms containing loops. The number of loops in each subprogram is
cleared when the subprogram ends. Refer to 5-5-23 G72: Subprogram Jump for
details.
