Access Machine Data Editor

Navigate to Commissioning > Machine > Machine Data and identify the parameter field mentioned in %1 variable of the alarm text.

Use the alarm detail view to see exactly which parameter field triggered the alarm

Check Parameter Limits

Press the Info key while cursor is on the parameter to display valid range. Compare current value against maximum limit shown.

Do not modify safety-related parameters without proper authorization

Correct Parameter Value

Enter a value within the valid range and press Input key. Reset alarm using Reset key on machine control panel.

Document original values before making changes for rollback purposes

Open Drive Commissioning

Navigate to Commissioning > Drive > Servo and locate the drive parameter that triggered the alarm using the %1 field reference.

Use STARTER integrated in SINUMERIK for detailed drive parameter access

Verify Drive Limits

Check drive nameplate data and compare against entered values. Access parameter limits via drive expert list in commissioning tool.

Incorrect drive parameters can cause motor damage or unsafe operation

Apply Correct Drive Values

Enter manufacturer-specified values within drive capability limits. Download parameters to drive using 'Copy RAM to ROM' function.

Use drive auto-commissioning first to establish baseline parameters

Access Tool Management

Navigate to Machine > Tool Management or Parameters > Work Offsets to locate the oversized coordinate value.

Check both geometry and wear offset values as both contribute to total offset

Validate Coordinate Ranges

Verify that tool length, radius, or work offset values are within ±99999.999mm range typical for SINUMERIK systems.

Extreme offset values can cause collision or coordinate system errors

Correct Offset Values

Enter realistic tool dimensions or work offset coordinates. Save changes and clear alarm using NC Reset.

Use tool measurement cycles to automatically determine accurate tool offsets

Identify Input Field

Note the specific HMI screen and input field where the alarm occurred. Check alarm buffer for %1 parameter details.

Alarm occurs immediately upon pressing Input key in the problematic field

Check Field Format

Verify the expected data format (integer, decimal places, sign) for the specific input field using HMI help function.

Some fields have different limits based on machine configuration

Re-enter Valid Data

Clear the field using Delete key and enter a value matching the expected format and range. Confirm with Input key.

Use Tab key to move between fields without triggering validation until all entries are complete
