Specify the number of the axes group to enable in the MC_GroupEnable (Enable Axes Group) instruc-
tion to enable operation instructions for an axes group in the user program. An instruction error occurs if
you execute a motion control instruction for an axes group that is not enabled. You can enable more
than one axes group at the same time, but if you enable more than one axes group that include the
same axis, an instruction error occurs.
If you want to operate the same axis in different axes groups for each work process, create multiple
axes groups that include that axis. You can then use the MC_GroupEnable (Enable Axes Group) and
MC_GroupDisable (Disable Axes Group) instructions to enable and disable these axes groups as you
need to use them.
If you execute the MC_GroupDisable (Disable Axes Group) instruction during multi-axis operation, the
axes in the group will decelerate to a stop.
Interpolation Accel-
eration Warning
Value Set the percentage of the maximum interpo-
lation acceleration at which to output an
interpolation acceleration warning. No inter-
polation acceleration warning is output if 0 is
set. (Unit: %) 0 to 100 0
Interpolation Decel-
eration Warning
Value Set the percentage of the maximum interpo-
lation deceleration rate at which to output an
interpolation deceleration warning. No inter-
polation deceleration warning is output if 0 is
set. (Unit: %) 0 to 100 0
Axes Group Stop
Method Set the stop method of the composition axes
for which an error did not occur when an
error occurs that forces an immediate stop of
an axis that is in a multi-axes coordinated
motion.
0: Immediate stop
1: Decelerate axes to a stop at maximum
deceleration rate of the axes
3: Immediate stop and Servo OFF
0, 1, or 3 0
Correction Allow-
ance Ratio This parameter applies when the center des-
ignation method is used for a circular inter-
polation instruction. It compensates the
distance when the distance between the
start point and the center point does not
equal the distance between the end point
and the center point. Set the allowable range
for that correction as a percentage of the
radius. Set the percentage to 0.1% or
greater. Error checking is not performed if 0
is set. Single-precision
floating-point num-
ber between 0 and
100 0
