1. AXIS CONTROL
B-64693EN-1/01
- 178 - CAUTION 1 When bit 2 (ZCL) of parameter No. 1201 is set to 1 and an axis returns to the reference point by the manual reference point return function, the zero point of the local coordinate system of the axis matches that of the work coordinate system. The same is true when the following command is issued: G52 a 0;
a : Axis which returns to the reference point 2 The local coordinate system setting does not change the workpiece and machine coordinate systems. 3 Whether the local coordinate system is canceled upon reset depends on the specified parameters. The local coordinate system is canceled upon reset when bit 6 (CLR) of parameter No. 3402 or bit 3 (RLC) of parameter No. 1202 is set to 1. In 3-dimensional coordinate conversion mode, however, the local coordinate system is not canceled when bit 2 (D3R) of parameter No. 5400 is set to 1. 4 When a workpiece coordinate system is set with the G code command for coordinate system setting (G92 <M series>, G50 <T series> (G92 with G code system B/C for T series)), the local coordinate system is canceled. However, the local coordinate system of an axis for which no coordinate system is specified in a G code block for coordinate system setting remains unchanged. 5 G52 cancels the offset temporarily in cutter or tool-nose radius compensation. 6 Command a move command immediately after the G52 block in the absolute mode.

ZCL
[Input type] Parameter input
[Data type] Bit path
#2 ZCL Local coordinate system when the manual reference position return is performed 0: The local coordinate system is not canceled. 1: The local coordinate system is canceled.
CAUTION ZCL is valid when the workpiece coordinate system is provided (when 0 is set in bit 0 (NWZ) of parameter No. 8136). In order to use the local coordinate system (G52), the workpiece coordinate system option is required.

#3 RLC Local coordinate system is 0: Not cancelled by reset. 1: Cancelled by reset.
