Alarm 10200

Siemens 10200 - [up to SW 3.x] Channel NC start with active alarm not allowed

SINUMERIK alarm 10200 fires when the servo drive detects motor current exceeding the configured limit in MD32200 (MAX_CURRENT_PERCENT) or the motor's rated current from MD32000 (RATED_CURRENT). The drive's current monitoring function compares actual output current against these thresholds and triggers protective shutdown to prevent motor or drive damage.

Root Cause Summary

SINUMERIK alarm 10200 fires when the servo drive detects motor current exceeding the configured limit in MD32200 (MAX_CURRENT_PERCENT) or the motor's rated current from MD32000 (RATED_CURRENT). The drive's current monitoring function compares actual output current against these thresholds and triggers protective shutdown to prevent motor or drive damage.

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. 1

    Verify Motor Nameplate Data

    Compare physical motor nameplate against HMI > Commissioning > Drive > Motor Data. Check MD32000 matches motor's rated current exactly.

    European motors often show current at 400V - verify voltage matches MD32100

  2. 2

    Check Current Limit Settings

    Navigate to HMI > Commissioning > Drive > Monitoring and verify MD32200 (MAX_CURRENT_PERCENT) is typically 150-200% of rated current.

    Never exceed 300% - can damage drive output stage

  3. 3

    Perform Motor Data Calculation

    Use HMI > Commissioning > Drive > Motor Data > Calculate to auto-populate motor parameters, then verify against nameplate.

    Always backup machine data before running motor calculations

  4. 4

    Test with Reduced Load

    Run axis at 10% rapid override to verify alarm clears with correct motor data - indicates parameter issue resolved.

DIY Feasiblehigh confidence

Call a technician if:

  • ·Drive hardware replacement needed
  • ·Motor replacement required
  • ·Complex mechanical repairs beyond basic adjustment

Prevention

  • Regular ballscrew lubrication per maintenance schedule
  • Monitor following error trends monthly
  • Verify motor parameters after any motor replacement
  • Keep drive cooling fans clean and functional

Common Mistakes

  • Setting MAX_CURRENT_PERCENT too low thinking it saves energy
  • Ignoring mechanical binding and only adjusting parameters
  • Not checking all three motor cable phases for damage
  • Using generic motor data instead of actual nameplate values
