Overview of Alarms
• Modify MD 1142: $MD_FIELD_WEAKENING_SPEED (threshold speed for field weak-
ening)
• Modify MD 1136: $MD_MOTOR_NOLOAD_CURRENT (motor no-load current)
• Modify MD 1119: $MD_SERIES_INDUCTANCE (series reactor inductance)
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department.
For standard motors: Reset the drive (delete the bootfile) and repeat the startup.
For third-party motors:
• Modify MD 1132: $MD_MOTOR_NOMINAL_VOLTAGE (motor voltage)
• Modify MD 1135: $MD_MOTOR_NOLOAD_VOLTAGE (motor no-load voltage)
• Modify MD 1400: $MD_MOTOR_RATED_SPEED (rated motor speed)
• Modify MD 1142: $MD_FIELD_WEAKENING_SPEED (threshold speed for field weak-
ening)
• Modify MD 1136: $MD_MOTOR_NOLOAD_CURRENT (motor no-load current).
• Call the SIEMENS AG, SIMODRIVE Hotline.
