Modulo limitation error of optional encoder

What does F2178 mean?

A modulo limitation error has occurred with the optional encoder. Similar to the motor encoder, this suggests that the optional encoder's position value has violated its defined modulo range, or an unexpected wrap-around. This can lead to incorrect position feedback for the system components relying on this optional encoder.

• Incorrect modulo parameters configured for the optional encoder
• Optional encoder counting issues or skipped pulses
• Uncommanded movement exceeding optional encoder modulo range limits
• Software error in optional encoder modulo position calculation
• Noise causing erroneous optional encoder readings

1. 1

   Inspect optional encoder cable for physical damage, proper shielding, and secure connections at both the encoder and IndraDrive terminals.

2. 2

   Measure the supply voltage to the optional encoder to ensure it is within the manufacturer's specified range.

3. 3

   Verify optional encoder configuration parameters (e.g., encoder type, resolution, modulo range, scaling factors) in the IndraDrive against the machine documentation.

4. 4

   Check for proper grounding of the optional encoder cable and drive system to mitigate potential electrical interference.
