Axor SHR140‑100W is a Eurocard‑formatted dumping card used on MINISPEED/Miniclamp rack drives to safely discharge regenerative braking energy back into the DC bus. Common failure modes include overheating of the integrated 200 W resistor or external 800 W dump resistor, capacitor degradation in the internal power path, and PCB trace burn‑outs from over‑voltage spikes. First‑check diagnostics: verify the DC bus voltage does not exceed the card’s rated limits with an oscilloscope; inspect the resistor and ceramic capacitors for discoloration or cracking; and confirm that all solder joints and vias are intact before powering the unit again.[oss-gpt-20b] |
