Safety
- Only qualified personnel should diagnose and clear control alarms; follow the machine builder's safety procedures and lockout/tagout where hardware work is required.
Causes and Fixes
- 1
SAFETY: Stop all operations and lock out machine
Ensure machine is in safe state before any diagnostics. Follow LOTO procedures.
- 2
Locate the error block
Check the alarm message for the specific line and channel/axis causing the issue.
- 3
Verify NCU assignment (technician recommended)
Have qualified personnel confirm the axis and drive NCU configuration. Do not modify without proper training.
- 4
Adjust program syntax only
Modify the G-code to avoid high-speed operations for affected axes. Do not change hardware configuration without technician.
Call a technician if:
- ·Before making any NCU configuration changes
- ·If unfamiliar with multi-channel Siemens systems
- ·If the alarm persists despite correct syntax
- ·Before modifying machine configuration parameters
Prevention
- Verify axis-drive NCU mapping before programming high-speed operations
- Use simulation to catch configuration mismatches early
Common Mistakes
- Overlooking NCU assignments in multi-channel setups
- Misinterpreting the alarm as a hardware issue
