(6) Reference position return ( 05h )
This command performs the same operation as manual reference position return of the
CNC after rapid traverse in the reference position return direction set by bit 5 (ZMIx) of
parameter No. 1006.
Reference position setting without DOG
If bit 1 (DLZx) of parameter No. 1005 for the function for setting the reference position
without dogs is set for each axis, and reference position return operation is not performed
even once after the power is turned on, a reference position return operation (positioning at
a grid closest to the current position) can be performed without using the reference position
return deceleration signal when a movement (positioning at a location near the reference
position) is made in the direction set for each axis with the continuous feed command
(EC0g to EC6g: 06h) and the reference position return command (EC0g to EC6g: 05h) is
specified.
At the time of positioning at a location near the reference position, the machine needs to be
moved in the reference position return direction at such a feedrate that the servo position
deviation exceeds the value set in parameter No. 1836.
The direction from a neighborhood point to a grid is set by bit 5 (ZMIx) of parameter No.
1006.
If the reference position return command (EC0g to EC6g: 05h) is issued after reference
position establishment, a high-speed reference position return operation is performed,
regardless of the reference position return direction set by bit 5 (ZMIx) of parameter No.
1006.
Specify this command after canceling cutter compensation and tool length compensation.
