Haas Alarm: 444 – REGEN ON TOO LONG – Haas Mill

Haas Alarm: 444 (M) REGEN ON TOO LONG – The power supply detected a condition in which the Regen stays active too long. This condition indicates that the incoming AC voltage is too high elevating the DC bus, that the regen load is open or disconnected, or there is excessive power being dumped by the spindle motor. This can also be caused by a Decel parameter too high. Check the connections and resistance of the Regen load, the incoming AC voltage and the value of Parameter 186. Cycle power to continue.
