%.1s z1 motor enc. ampl. too small

What does 2204 F210 mean?

The Z1 amplitude of the motor encoder (ERN 1381) for the displayed axis is too small. This indicates a problem with the encoder signal integrity, potentially leading to inaccurate position feedback.

• Z1 amplitude of the motor encoder (ERN 1381) for the displayed axis is too small.

Click steps to track your progress.

1. 1

   Check the motor encoder (ERN 1381) cabling for the specified axis, including shielding and ground connections, for damage, loose contacts, or interference.

2. 2

   Inspect the encoder itself for signs of physical damage, contamination (e.g., oil, dust), or mounting issues that could affect signal generation.

3. 3

   Verify the power supply voltage to the encoder is present and stable, within the specified operating range.

4. 4

   If possible, use an oscilloscope to measure the Z1 signal amplitude directly at the encoder output and at the control input to detect signal degradation.
