Position Control Range Trip

What does E83. mean?

This fault occurs during simple position control if the motor's current position deviates outside the range defined by the 'Position Limit Setting' (P072 and P073). This indicates that the motor has moved beyond its acceptable positional boundaries, usually due to incorrect settings, external forces, or a malfunction in the positioning system, requiring a shutdown for safety.

• Incorrectly set position limits P072 (Lower Position Limit) and P073 (Upper Position Limit), not matching the mechanical travel range.
• Motor shaft not rotating as commanded due to mechanical binding, excessive load, or slippage in the drive train.
• Loss of encoder pulses or inaccurate encoder feedback, causing the inverter to miscalculate the motor's actual position.
• Insufficient motor torque or acceleration/deceleration times (e.g., P007, P008) to reach commanded position within expected tolerance.
• Commanded target position (e.g., through digital input or communication) is outside the defined P072/P073 range.

Click steps to track your progress.

1. 1

   1. Verify parameters P072 (Lower Position Limit) and P073 (Upper Position Limit) accurately reflect the physical travel limits of the mechanical system.

2. 2

   2. Manually move the mechanical system through its full range of motion to confirm no binding or obstructions are present.

3. 3

   3. Check the encoder connection for security and use an oscilloscope to verify consistent A/B phase pulse generation during motor movement.

4. 4

   4. Monitor the motor's current position feedback (e.g., display parameter d005) and compare it against the commanded position.

5. 5

   5. Adjust acceleration and deceleration times (e.g., P007, P008) to provide smoother transitions and prevent overshoot/undershoot.

6. 6

   6. Increase motor current limit (e.g., P1-07) or tune current loop gains (if available) to ensure sufficient torque delivery.
