9 MAJOR POSITIONING CONTROL
9.2.5 4-axis linear interpolation control
In "4-axis linear interpolation control" (" Da.2 Control system" = ABS linear 4, INC
linear 4), four motors are used to carry out position control in a linear path while
carrying out interpolation for the axis directions set in each axis.
(Refer to section "9.1.6 Interpolation control" for details on interpolation control.)
[1] 4-axis linear interpolation control (ABS linear 4)
In the absolute system 4-axis linear control, using an address established by a
machine OPR in the 4-axis coordinate space, a linear interpolation positioning is
carried out from the current stop position (start point address) to the address (end
point address) set in the " Da.6 Positioning address/movement amount".
Restrictions
An error will occur and the positioning will not start in the following cases. The
machine will immediately stop if the error is detected during a positioning control.
•
When the movement amount for each axis exceeds "1073741824 (=2
30
)"
An "outside linear movement amount range error (error code: 504)" will occur at
the positioning start.
(The maximum movement amount that can be set in " Da.6 Positioning
address/movement amount" is "1073741824 (=2
30
)".)
