9.2.5 4-axis linear interpolation control

MELSEC-Q

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.

•If the movement amount of each axis exceeds "1073741824 (=230)" when "0: Composite speed" is set in " Pr.20 Interpolation speed designation method"

... The "Outside linear movement amount range error (error code: 504)" occurs at a positioning start.

(The maximum movement amount that can be set in " Da.6 Positioning address/movement amount" is "1073741824 (=230)".)
