Motor Stalled

What does F006 mean?

The drive is unable to successfully accelerate or decelerate the motor to the commanded speed, indicating a motor stall condition. This typically happens when the mechanical load is too high, or acceleration/deceleration ramps are set too aggressively, causing the output current to exceed limits for an extended period. This risks motor and drive damage from overheating.

• Severe mechanical binding or obstruction in the driven machinery (e.g., seized bearings, jammed conveyor belt, material blockage).
• Motor shaft or mechanical coupling failure, leading to a loss of mechanical connection between the motor and the load.
• Parameter P1-54 (Stall Current Limit) set too low, causing the drive to trip prematurely before the motor can overcome the load inertia.
• Motor overload condition where the application's torque demand continuously exceeds the motor's capability, preventing acceleration.
• Incorrect motor parameters (e.g., P1-50 [Motor Nominal Current], P1-51 [Motor Nominal Speed]) causing inaccurate torque estimation.

Click steps to track your progress.

1. 1

   Disconnect the motor from the mechanical load and attempt to run the motor unloaded, observing the motor current (P0-04 [Motor Current]) and speed (P0-01 [Motor Speed]).

2. 2

   Manually rotate the motor shaft and connected mechanical load (if accessible) to identify any binding, excessive friction, or obstructions.

3. 3

   Increase the stall current limit (P1-54 [Stall Current Limit]) in 5% increments relative to the motor's nominal current (P1-50 [Motor Nominal Current]), ensuring it remains within safe motor limits.

4. 4

   Verify all motor parameter settings (P1-50 [Motor Nominal Current], P1-51 [Motor Nominal Speed], P1-52 [Motor Nominal Voltage]) are accurately programmed according to the motor nameplate.

5. 5

   Increase the acceleration time (P2-01 [Acceleration Time]) by 1-2 seconds to allow the motor more time to overcome inertia and reach commanded speed.
