RS-485 Interrupt
The main circuit DC voltage becomes lower than the low voltage
detection level (Cn-34).
The inverter output current becomes approx. 200% and above the
inverter rated current.
A ground fault occurs at the inverter output side and the ground-fault
current exceeds approx. 50% of the inverter rated current.
The main circuit DC voltage becomes excessive because of
regeneration energy caused by motor decelerating.
The temperature of the cooling fin reaches the detection level.
Motor overload is detected by the electronic thermal relay.
(motor protection)
The electronic thermal sensor detects inverter overload while the
output current exceeds 112% of rated value. (inverter protection)
Over torque is detected while the output current is larger than or
equal to the setting of Cn-26. (machine protection)
