Motor Overload Protection
Electronic thermal overload relay
Instantaneous Over Current
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
Over Voltage
Motor coasts to a stop if DC bus voltage exceed
820V
Under Voltage
Stops when DC bus voltage is approx. 400V or less
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)
