6.18 LINEAR INTERPOLATION (G28, G30, G53)
Overview
When positioning operation of linear interpolation type is specified
(parameter LRP (No. 1401#1) = 1), the following operations can also
be set as operations of linear interpolation type by setting parameter
ZRL (No. 1015#4) to 1:
- Movement from an intermediate point to a reference position in
automatic reference position return operation (G28)
- Movement from an intermediate point to a reference position in
second, third, or fourth reference position return operation (G30)
- Positioning by machine coordinate system selection (G53)
When any of the operations above is set as an operation of linear
interpolation type, acceleration/deceleration control follows the setting
of parameter RCT (No. 1603#4).

# 4 ZRL When a reference position is established, the tool path from the middle
point to the reference position and machine coordinate positioning
(G53) in automatic reference position return (G28) are based on:
0: Positioning of nonlinear interpolation type
1: Positioning of linear interpolation type

[Data type] Bit path
# 4 PRT For positioning of linear interpolation type:
0: Acceleration/deceleration of acceleration fixed type is used.
1: Acceleration/deceleration of time fixed type is used.
