Status indicator LED: RUN and ALARM provided as standard LED's
Digital operator: available to monitor frequency reference, output frequency, output current
Motor coasts to a stop at approx. 250% of inverter rated current
Motor coasts to a stop after 1 minute at 150% of inverter rated output current
Motor coasts to a stop if DC bus voltage exceed 410 V (double for 400 V class)
Stops when DC bus voltage is approx. 200 V or less (double for 400 V class)
Following items are selectable: Nnot provided (stop if power loss is 15ms or longer),
continuous operation if power loss is approx. 0.5 s or shorter, continuous operation
Individual level stall prevention can be set during acceleration or constant running,
provided/not provided setting available during deceleration.
Protected by electronic circuit (operation level is approx. 250% of rated output current)
