6. INTERPOLATION FUNCTION
B–64113EN–1/01
364
When positioning operation of linear interpolation type is specified (bit
1 (LRP) of parameter No. 1401 = 1), the following operations can also be
set as operations of linear interpolation type by setting bit 4 (ZLN) of
parameter No. 1015 to 1:
D Movement from an intermediate point to a reference position in
automatic reference position return operation (G28)
D Movement from an intermediate point to a reference position in
second, third, or fourth reference position return operation (G30)
D 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
bit 4 (RCT) of parameter No. 1603.

[Data type] Bit
ZLN When positioning of linear interpolation type is specified (bit 1 (LRP) of
parameter No. 1401 = 1), automatic reference position return operation
(G28), second to fourth reference position return operation, and machine
coordinate system selection are set as:
0 : Positioning of non–linear interpolation type.
1 : Positioning of linear interpolation type.
This parameter is valid when bit 1 (LRP) of parameter No. 1401 = 1.

[Data type] Bit
RCT When positioning of linear interpolation type is specified (bit 1 (LRP) of
parameter No. 1401 = 1), acceleration/deceleration control is based on:
0 : Constant acceleration/deceleration method.
1 : Constant time (time constant) method.
