Following items are selectable: Not provided (stops if power loss is
15 ms or longer), continuous operation if power loss is approx. 0.5
s or shorter, continuous operation.
Protected by electronic circuit.
Can be set individual levels during acceleration/deceleration, pro-
vided/not provided available during coast to a stop.
Protected by electronic circuit (fan lock detection).
Protected by electronic circuit (rated output current level).
Charge LED is provided.
ON until the DC bus voltage becomes 50 V or less.
