F1018 fault in siemens sinamics V90 drive

-
F1018 fault in siemens sinamics V90 drive indicates Booting has been interrupted several times. This means the drive failed to complete its startup sequence repeatedly, often due to power instability or corrupted parameters, and has booted with factory settings. 

Cause:
Module booting was interrupted several times. As a consequence, the module boots with the factory setting.
Possible reasons for booting being interrupted:
  • Power supply interrupted.
  • CPU crashed.
  • Parameterization invalid.
After this fault is output, then the module is booted with the factory settings.

Remedy:
  • Carry out a POWER ON (power off/on). After switching on, the module reboots from the valid parameterization (if available).
  • Restore the valid parameterization.
Examples:
  • Carry out a first commissioning, save, carry out a POWER ON (switch-off/switch-on).
  • Load another valid parameter backup (e.g. from the memory card), save, carry out a POWER ON (switch-off/switch-on).
Note: If the fault situation is repeated, then this fault is again output after several interrupted boots.

3210 DC bus overvoltage fault in lenze i550 drive

-
Fault Code 3210 in a Lenze i550 drive indicates a DC bus overvoltage fault . This means the voltage on the DC bus within the drive has exceeded its safe operating limit. Potential Causes Drive Internal Components: A fault in the drive's rectifier, smoothing capacitor, or control circuitry. Solution: This often requires professional inspection and repair or replacement of the faulty component. Power Supply Issues: Excessive AC voltage input to the drive. Solution: Check the power supply for voltage fluctuations or overvoltage conditions. Motor Issues: A short circuit or other fault within the motor can cause excessive back EMF, leading to DC bus overvoltage. Solution: Inspect the motor for any signs of damage or malfunction. Drive Configuration Issues: Incorrectly configured drive parameters, such as excessive regeneration or improper motor data. Solution: Review and adjust drive parameters to match the motor and application requirements. Troubleshooting Steps Check Power ...

7180 Motor overcurrent fault in lenze i550 drive

-
Fault Code 7180 in a Lenze i550 drive indicates a motor overcurrent fault . This means the motor connected to the drive is drawing more current than its rated capacity, which can lead to overheating and potential damage. Potential Causes Overloaded Motor: The motor is being asked to do more work than it's designed for. Solution: Reduce the load on the motor or ensure it's rated for the required power. Mechanical Issues: Jamming: The motor or its connected machinery might be jammed, causing excessive current draw. Friction: Increased friction due to misalignment or worn components can lead to higher currents. Solution: Check for mechanical obstructions, ensure proper alignment, and replace worn parts if necessary. Electrical Problems: Short Circuit: A short circuit within the motor windings can cause excessive current. Incorrect Wiring: Improper connections can lead to overloading. Solution: Inspect for short circuits, verify wiring diagrams, and correct any issue...

FF06 Motor overspeed fault in lenze i550 drive

-
Fault Code FF06 in a Lenze i550 drive indicates a motor overspeed fault . This means the motor connected to the drive is spinning at a speed that exceeds its rated maximum speed. Potential Causes Drive Configuration Issues: Incorrectly set maximum speed limit or frequency. Solution: Verify and adjust drive parameters to match the motor's specifications. Mechanical Problems: Jamming or Binding: Obstructions in the mechanical system can cause the motor to accelerate beyond its rated speed. Loose Coupling: A loose coupling between the motor and the driven load can lead to overspeed. Solution: Check for mechanical obstructions, ensure proper alignment, and tighten couplings as needed. Sensor Issues: A faulty speed sensor or incorrect sensor calibration can provide inaccurate speed readings, leading to overspeed. Solution: Verify the sensor's functionality, calibrate it if necessary, or replace it if faulty. Drive Internal Components: A fault within the drive's contr...
