%.1s motor encoder freq. too high
Heidenhain · NC Control
What does 2208 F2A0 mean?
The input frequency of the motor encoder for the displayed axis is incorrect, specifically too high. This can lead to erroneous speed and position feedback.
Common Causes
- Input frequency of the motor encoder for the displayed axis is incorrect.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Use an oscilloscope to measure the actual input frequency of the motor encoder signal at the NC control's input terminal for the affected axis.
- 2
Compare the measured frequency to the expected maximum frequency specified in the motor/encoder or NC control manual.
- 3
Inspect the motor encoder cable for any signs of damage, poor shielding, or external interference that could generate erroneous high-frequency signals.
- 4
Verify that the encoder and the NC control's input stage are compatible in terms of maximum operating frequency and signal type.
