functions
Overload Motor coasts to a stop for 1 minute at 150% rated output
current
Motor overload protection Electronic thermal overload relay
Overvoltage Motor coasts to a stop if converter output voltage exceeds
410 V.
Undervoltage Motor coasts to a stop if the converter output voltage of a
3-phase model drops to 210 V or below and that of a
single-phase model drops to 170 V or below.
Ground fault Provided by electronic circuit.
Momentary power loss Immediately stops if 15 ms or more momentary power
loss. Resumes operating after a power loss period of
approximately 2 s if the input is 1.5 kW or more and
approximately 1 s if the input is 0.75 kW or less in a certain
mode.
Heat sink fin overheat Protected by thermistor
Power charge indication Charge lamp stays ON until bus voltage drops below 50 V.
