functions
Overload
Motor coasts to a stop for 1 minute at 150% rated output
current
Ground fault
Provided by electronic circuit.
Motor overload protection
Electronic thermal overload relay
Overvoltage
Motor coasts to stop if main circuit DC voltage exceeds
820 V.
Undervoltage
Stops if the main circuit DC voltage is approx. 420 V or less.
Momentary power loss
Immediately stops if 15 ms or more momentary power loss.
Resumes operating after a power loss period of approxi-
mately 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.
Cooling fin overheat
Protected by thermoswitch (only for forced cooling method)
Power charge indication
CHARGE indicator stays ON until main circuit DC voltage
drops below 50 V.
