What does 089 mean?

The rotor position adjustment was canceled, possibly due to an Sd7 or Sd8 error occurring during the adjustment with an absolute value encoder. This error is saved with mains failure protection.

• Prior encoder fault (Sd7/Sd8): An active or transient Sd7 (absolute encoder initialization error) or Sd8 (encoder timeout) fault occurred during the rotor position identification routine, leading to its cancellation.
• Mechanical obstruction: The motor or connected load encountered a mechanical bind or obstruction during the rotor position adjustment sequence, preventing free rotation.
• Insufficient motor torque: The motor's torque capability (or drive current limit, e.g., P2-01) was insufficient to overcome static friction or inertia during the adjustment, leading to an aborted sequence.
• Incorrect motor parameters: Motor nameplate data (e.g., P3-01 to P3-06 for rated current, voltage, speed) entered into the drive are incorrect, causing the adjustment routine to miscalculate.
• Power interruption: A brief power sag or interruption occurred during the rotor position adjustment process, causing the drive to reset or abort the procedure.

Click steps to track your progress.

1. 1

   Clear any active or pending encoder-related faults (e.g., Sd7, Sd8) first, then re-initiate the rotor position adjustment (e.g., using P0-10 or dedicated commissioning wizard).

2. 2

   Mechanically inspect the motor and connected load to ensure there are no physical obstructions or excessive friction preventing smooth rotation during the adjustment.

3. 3

   Verify all motor nameplate parameters (e.g., P3-01 to P3-06 for motor type, rated current, voltage, speed) are correctly entered into the drive.

4. 4

   Temporarily increase the drive's current limit (e.g., P2-01) or ensure sufficient torque is available to complete the rotor position adjustment, then reset to normal.

5. 5

   Monitor the control voltage supply (e.g., 24VDC) to the drive during the rotor position adjustment procedure to ensure stability and prevent unexpected resets.
