Motor Overload Protection Electronic thermal overload relay
Instantaneous Overcurrent
Motor coasts to a stop at approx. 200% of inverter rated
current
Overload
Motor coasts to a stop after 1 minute at 150% of inverter rated
output current
Overvoltage Motor coasts to a stop if DC bus voltage exceed 410V
Undervoltage
Stops when DC bus voltage is approx. 200V or less (approx.
160V or less for single-phase series)
Momentary Power Loss
Following items are selectable: Not provided (stops if power
loss is 15ms or longer), continuous operation if power loss is
approx. 0.5s or shorter, continuous operation
Cooling Fin Overheat Protected by electronic circuit
Stall Prevention Level
Individual levels during accel/running, enable/disable provided
during deceleration
Cooling Fan Fault Protected by electronic circuit (fan stalling detection)
Ground Fault Protected by electronic circuit (rated output current level)
