| Protection |
Overcurrent
(Short-circuit)
(Ground fault) |
Protects and stops the inverter when the following overcurrent
flows during acceleration, deceleration, or constant speed rotation:
- Overcurrent caused by overload
- Overcurrent caused by short-circuit in output circuit
- Overcurrent caused by ground fault
| * |
Ground fault can be detected at starting. |
|
|
| Overvoltage |
Stops the inverter by detecting overvoltage in DC link circuit
during braking.
| * |
230V series: 460V DC 400V series: 800V DC |
|
|
| Incoming surge |
Protects the inverter from surge voltage entering between main
circuit power cable and earth cable. |
|
| Undervoltage |
Stops the inverter by detecting voltage drop in DC link circuit.

Details of operation can be selected with the function code F14. |
|
F14 |
| Input phase loss |
Stops or protects the inverter against input phase loss.
| * |
Non-operation is also selectable. |
|
H98 |
| Output phase loss |
Stops the inverter by detecting output phase loss at the start
of or during operation.
| * |
Non-operation is also selectable. |
|
H98 |
| Overheating |
(Heat sink) |
Stops the inverter by detecting inverter heat sink temperature. |
|
| (Braking resistor) |
Stops the inverter and built-in braking transistor if "discharging
capability" or "allowable loss" set for the braking resistor is
exceeded more frequently than the set number of times. |
F50
F51 |
| Overload |
Stops the inverter by detecting the output current and internal
temp. To calculate the IGBT internal temp. |
|
Motor
protection |
(Electronic thermal) |
Stops the inverter to protect the motor when the set output.
Current is exceeded.
| * |
Thermal time constant can be adjusted (0.5
to 75.0min). |
|
F10 to F12 |
| (PTC thermistor) |
A PTC thermistor input stops the inverter to protect the motor. |
H26, H27 |
| (Overload early warning) |
Warning signal can be output based on the set level before
the inverter trips.

| Retry function |
When the motor is tripped and stopped, this function automatically
resets the tripping state and restarts operation. Activated when the motor is
tripped with the following trip codes:
 . . . . . . . . . .
| * |
Waiting time before resetting and the number
of retry times can be set. |
