Fagor alarm 5006: Error because the node has been reset

What it means

Fagor documents this 8055 CAN error when a bus node reboots because its power supply collapsed momentarily. All motion is stopped and enables are removed. The fix is to stabilize the node supply rather than replace the module first.

Likely causes

• undimensioned or failing 24 VDC supply feeding the remote group
• poor 0 V / ground connection at the node
• output load on the node dragging the supply down

Replacement parts

We supply the following units for this alarm — tested, warranty-backed:

• RIO70 power-supply module (one required per group)
