ERROR CODE D1010 Regenerative resistor over-heat [XX].
The thermal switch for the power block regenerative resistor unit, or the optional regen-
erative resistor unit reached 140° C (284°F), or the heat sink thermal switch reached
90° C (194°F), or the controller cabinet thermal switch reached 70° C (158° F). The
thermal switches are wired in series and the AS software cannot distinguish which
thermal switch is activated. For D7X controller, if the heat exchange fan is inoperative
(X207 disconnected) this error is generated.

Main causes include:
1. High inertia loads due to excessive tool weight or incorrect program data.
2. Defective cooling fans.
3. Insufficient clearance for air circulation.
4. High ambient controller temperature.
5. Defective power block.
6. Disconnected or defective harness between the 1KC/1KD board and the additional
regenerative resistor unit.
7. Defective regenerative resistor unit.
8. Defective additional regenerative resistor unit.
9. Defective 1KB board.
10. Disconnected or defective harness between X211 or X212 on the 1KX/1NX board
and X501 or X502 on the power block.
