Communication between the spindle sensor and the spindle amplifier is not performed. This indicates a problem in the data transmission/reception path between these components, preventing normal operation and potentially leading to unexpected machine behavior.
Click steps to track your progress.
Verify the physical connection of the sensor cable between the spindle sensor and the spindle amplifier for proper seating.
Inspect the sensor cable for any signs of physical damage, kinks, or loose contacts on its connectors.
If the cable appears intact and securely connected, attempt to reset the alarm after ensuring the physical connection is stable.
If the alarm persists, replacement of the spindle sensor or the spindle amplifier may be necessary, as a component might be faulty (refer to page 13 for general component replacement advice).
