Encoder 2 failure: quadrant error

What does F245 mean?

The DIAX04 SSE-03VRS drive's secondary encoder (Encoder 2) has detected an invalid sequence or state in its quadrature signals (A, B channels). Similar to Encoder 1 quadrant error, this indicates an issue with the encoder's signal generation or its wiring, leading to unreliable position or velocity feedback. The drive faults to maintain control integrity.

• Damage to the encoder 2 cable, resulting in an open circuit, short circuit, or signal interference between phases A and B.
• Faulty encoder 2 unit, producing incorrect quadrature signals.
• Loose or corroded connections at the encoder or at the DIAX04 SSE-03VRS drive's encoder input terminals.
• Excessive electrical noise or interference on the encoder feedback lines, disrupting signal integrity.
• Improper termination or grounding of the encoder cable shield.

Click steps to track your progress.

1. 1

   Inspect the encoder 2 cable for any physical damage, kinks, or crushing. Verify continuity and check for shorts between signal lines and ground.

2. 2

   Check all connections at both the encoder and the DIAX04 SSE-03VRS drive for looseness, corrosion, or incorrect wiring.

3. 3

   Verify the encoder supply voltage at the encoder connector. Ensure it is stable and within the encoder's specified range.

4. 4

   Monitor the encoder A/B signals using an oscilloscope, if possible, to check for clean quadrature signals without dropouts or noise.

5. 5

   Ensure proper shielding and grounding of the encoder cable to minimize electrical interference. If the issue persists, consider replacing encoder 2.
