Navigate to SYSTEM > PMC > PMCPRM > DATA TABLE or SYSTEM > PARAM > ATC to view magazine registration. Check if the requested tool number exists in the magazine table (typically parameters 13200-13231 series for magazine pot assignment or PMC D-register based tables).

Access the tool magazine screen (SYSTEM > ATC or custom OEM screen) to verify tool pot assignments. Ensure the tool number matches exactly what is called in the NC program (T-code).

If tool is physically present but not registered, update magazine data through the ATC registration screen or by editing PMC keep relay data (typically K900-K999 range depending on machine builder). Register tool number to correct pot number.

Ensure machine is in EMERGENCY STOP before manually editing magazine data to prevent unexpected ATC operations.

After updating magazine data, perform a magazine origin search or tool pot recount via PMC function (typically G311 or machine builder-specific M-code) to synchronize physical magazine position with CNC data.

Check parameter 13000 (tool number of digits: typically 2-4 digits) and parameter 13001 (tool number coding method: 0=direct, 1=BCD, 2=binary). Verify settings match the machine tool magazine design specification.

Navigate to SYSTEM > PARAM and verify parameter 13003 (maximum tool number) is set correctly. If calling tool T25 but parameter 13003 is set to 20, the alarm will trigger.

Check parameter 13002 (tool management method: 0=magazine management, 1=random ATC, 2=tool life management). Ensure it matches the actual machine configuration and magazine type installed.

If using tool life management (parameter 13002=2), verify the tool is registered in OFFSET/SETTING > TOOL LIFE screen with correct tool number and group assignment.

Enter PMC diagnostics via SYSTEM > PMC > PMCDGN > SIGNAL and monitor the magazine tool detection signals (typically G-addresses or I-addresses for pot sensors). Manually rotate magazine and verify each pot sensor transitions correctly.

Check PMC ladder logic in SYSTEM > PMC > PMCPRG > LADDER for the tool search subroutine (often subprogram P50-P60 range). Verify the logic correctly reads tool pot data from keep relays and compares with requested tool number from CNC (typically F-register or R-register).

Do not modify PMC ladder without backup and full understanding of ATC interlock logic.

Inspect physical magazine pot sensors (typically inductive proximity sensors or mechanical switches). Check wiring to I/O board for continuity and proper voltage (typically 24VDC). Replace faulty sensors if detected.

Clear PMC keep relay tool data and perform a full magazine tool registration reset via machine builder's initialization procedure (typically holding specific panel buttons during power-on or executing a specific M-code sequence documented in machine manual).

This will erase all current tool magazine data and require complete re-registration of all tools.
