round-fault
current exceeds approx. 50% of the inverter rated current.
Operation
Fault
Over Voltage
The main circuit DC volta
g
e becomes excessive because of
regeneration energy caused by motor decelerating.
Operation
Fault
Over Heat
The temperature of the cooling fin reaches the detection level. Operation
Fault
Motor Over Load
Motor overload is detected by the electronic thermal relay.
(motor protection)
Operation
Fault
Inverter Over Load
The electronic thermal sensor detects inverter overload while the
output current exceeds 112% of rated value. (inverter protection)
Operation
Fault
Over Torque
Over torque is detected while the output current is larger than or
equal to the setting of Cn-26. (machine protection)
