Siemens 300888 - Axis drive parameterization error in current control adaption
This alarm occurs when the upper current limit in MD 1181 is set lower than the lower current limit in MD 1180, causing a parameterization error in current control adaption. Correct the values in the machine data to resolve it.

Siemens 300888 - Axis drive parameterization error in current control adaption
Axis drive parameterization error in current control adaption
The upper current limit in MD 1181: $MD_CURRCTRL_ADAPT_CURRENT_2 (upper adaption current limit) is less than the lower current limit in MD 1180: $MD_CURRCTRL_ADAPT_CURRENT_1 (lower adaption current limit) Control reaction: Interface signals are set. Alarm display.
Root Cause Summary
This alarm occurs when the upper current limit in MD 1181 is set lower than the lower current limit in MD 1180, causing a parameterization error in current control adaption. Correct the values in the machine data to resolve it.
Safety
- Drive/power/encoder circuit: hazardous voltages may remain in the DC link after power-off. Lock out / tag out, wait for discharge per the drive documentation, and use qualified personnel only.
Causes and Fixes
- 1
Access machine data
Navigate to the machine data settings in the Siemens control panel.
- 2
Verify and correct values
Ensure MD 1181 ($MD_CURRCTRL_ADAPT_CURRENT_2) is greater than MD 1180 ($MD_CURRCTRL_ADAPT_CURRENT_1). Adjust as needed.
- 3
Save and restart
Save the changes, clear the alarm, and restart the system to apply the new settings.
Call a technician if:
- ·If the alarm persists after correcting machine data values
- ·If access to machine data is restricted or unclear
Prevention
- Validate machine data settings before running programs
- Avoid program commands that alter critical machine data without verification
- Implement access controls to prevent unauthorized machine data modifications
- Document all parameter changes with proper authorization
Common Mistakes
- Overlooking the relationship between MD 1180 and MD 1181
- Failing to save changes after adjusting machine data
