3G3MV Inverters
Inverter PLC Specifications
Protective functions
Motor overload protection UL-recognized electronic thermal overload relay
Instantaneous overcurrent Motor coasts to a stop at approximately 250% inverter rated current
Overload Motor coasts to a stop after one minute at 150% rated output current
Overvoltage Motor coasts to a stop if DC bus voltage exceeds 410 V Motor coasts to a stop if DC bus voltage exceeds 820 V
Undervoltage Stops when DC bus voltage is approximately 200 V or
less (approx. 160 V or less for single-phase series)
Stops when DC bus voltage is approximately 400 V or
less
Momentary power loss Stops if power loss is 15 ms or more. By setting inverter, operation can be continued if power is restored within
approximately 0.5 s
Cooling method Cooling fan is provided for the following models:
200 V, 0.75 kW or larger inverters (3-phase)
200 V, 1.5 kW or larger inverters (single-phase)
Others models are self-cooling
Cooling fin overheat Protected by electronic circuit
Cooling fan fault Protected by electronic circuit (fan lock detection)
Stall prevention Individual levels during acceleration/running, enable/disable provided during coast to a stop
Ground fault Protected by electronic circuit (overcurrent level)
Power charge indication ON until the DC bus voltage becomes 50 V or less. RUN lamp stays ON or digital operator LED stays ON.
