Protection functions
Motor overload protection Electronic thermal overload relay
Instantaneous overcurrent Motor coasts to a stop at approx. 250% of inverter rated current
Overload
Heavy Duty: Motor coasts to a stop after 1 minute at 150% of inverter rated output current
Normal Duty: Motor coasts to a stop after 1 minute at 120% of inverter rated output current
Overvoltage Motor coasts to a stop if DC bus voltage exceed 410 V (double for 400 V class)
Undervoltage
Stops when DC bus voltage is approx. 190 V or less (double for 400 V class)
(approx. 150 V or less for single-phase series)
Momentary power loss
Following items are selectable: not provided (stop if power loss is 15 ms or longer), continuous operation if power loss is
approx. 0.5 s or shorter, continuous operation
Cooling fin overheat Protected by thermistor
