ing resistor, braking transistor built-in)
Possible to program any V/f pattern
Electronic thermal overload relay
Motor coasts to a stop at approx. 250% or more of Inverter rated current
Motor coasts to a stop after 1 minute at 150% of Inverter rated output cur-
rent
Motor coasts to a stop if DC bus voltage exceeds 820 V
Stops when DC bus voltage is approx. 400 V or less
The 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 short-
er, continuous operation.
Protected by electronic circuit.
Can be set to individual levels during acceleration/constant-speed opera-
tion, provided/not provided available during deceleration.
Protected by electronic circuit (fan lock detection).
Protected by electronic circuit (overcurrent level).
ON until the DC bus voltage becomes 50 V or less. Charge LED is pro-
vided.
