Main causes include:
1. High inertia loads due to excessive tool weight or incorrect program data.
2. Defective regenerative resistance control circuit, overheat failure of regenerative
resistance unit, defective voltage monitoring circuit, or defective power block.
3. Defective servo board (1KB board) or harness.
4. Defective additional regenerative resistance unit.
⇒
Reteach program steps to eliminate sudden high speed direction changes (dynamic
shock).
⇒
Replace the regenerative unit.
⇒
Replace the 1KB board, power block or harness.
⇒
Replace the additional regenerative resistor unit.
