Missing DSP Axis Card

What does SRVO-221 mean?

A controlled axis card (DSP) corresponding to the configured number of axes is not physically mounted or detected. This indicates a hardware configuration mismatch or a faulty axis control card.

• A DSP (Digital Signal Processor) axis card is missing from its designated slot in the servo drive or control system.
• The system expects a DSP card for processing axis commands, and its absence prevents the associated axis from functioning.
• This can occur if the card was not installed correctly, has become dislodged, or has failed and been removed.
• Requires verifying the presence and proper seating of the DSP axis card.
