PS0056

Review the NC program at the line triggering PS0056. Check if G17 (XY plane), G18 (ZX plane), or G19 (YZ plane) is commanded before the canned cycle block.

Navigate to CURRENT (POSITION screen) and verify the active G-code modal state. Press the SYSTEM softkey, then CURRENT. Check Group 02 for active plane code (G17/G18/G19).

Insert the appropriate plane selection code in the program before the canned cycle. For vertical machining (Z-axis drill): use G17. For horizontal machining (X or Y-axis drill): use G18 or G19 accordingly.

Verify parameter 5101 bit 4 (G17/G18/G19 plane selection valid) is set to 1. Access via SYSTEM > PARAM > [5101] and confirm bit configuration allows plane selection commands.

Changing parameter 5101 requires parameter write enable (PWE) bit 0 in setting 8. Incorrect settings may affect all program geometry.

Identify the canned cycle axis in the alarm block. Check which axis is specified for the drilling operation (typically the third axis: Z in G17, X in G18, Y in G19).

Verify plane/axis compatibility: G17 (XY plane) requires Z-axis canned cycle; G18 (ZX plane) requires Y-axis canned cycle; G19 (YZ plane) requires X-axis canned cycle. Cross-check program logic.

Correct the program by either changing the plane selection code to match the intended drilling axis, or modify the canned cycle to use the axis perpendicular to the active plane.

Check parameter 5130 (canned cycle initial level return plane) and parameter 5102 (automatic corner override) for any custom configurations that may affect canned cycle axis interpretation.

Examine the complete canned cycle block for proper format: G8X X__ Y__ Z__ R__ (for G17). Ensure all required addresses are present and numerical values are valid.

Check for conflicting modal G-codes in the same block. Navigate to PROGRAM > display the alarm block and verify no G-code group conflicts exist (e.g., multiple Group 01 codes).

Verify parameter 5102 bit 1 (which controls canned cycle Z-axis direction) matches the machine configuration. Access SYSTEM > PARAM > [5102] and confirm bit settings align with machine tool type.

Parameter 5102 bit settings are machine-specific. Document original values before changes.

Test with a simplified canned cycle: G90 G17 G81 X0 Y0 Z-10 R5 F100; followed by G80. If this executes without PS0056, the original program has syntax errors requiring line-by-line review.
