Explanation
Overcurrent
Stops the drive by detecting overcurrent caused by overload in the output circuit.
Short-circuit
Stops the drive by detecting overcurrent caused by short-circuit in the output circuit.
Ground fault
Stops the drive by detecting overcurrent caused by ground fault in the output circuit. (Detected when the
drive is started.)
Overvoltage
Stops the drive by detecting overvoltage (100V/200V series: 400 Vdc, 400V series: 800V) in dc link circuit.
Incoming surge
Protects the drive from surge voltage entering between main circuit power cable and earth cable.
Undervoltage
Stops the drive by detecting voltage drop (100V/200V series: 200V DC, 400V series: 400V) in dc link circuit.
Input phase loss
Stops the drive against input phase loss (by simply detecting the ripple voltage at a capacitor).
Output phase loss
Stops the drive by detecting output cable's phase loss at the start of operation or during operation.
Overheating
Stop the drive by detecting drive heat sink temperature caused by a failure or overload of the cooling fan.
Stops the drive and built-in braking transistor if "discharging capability" or "allowable loss" set for the
braking resistor is exceeded more frequency than the set number of times.
Overload
Stops the drive by calculating the IGBT internal temperature from the output current and drive heat sink
temperature.
Electric
Stops the drive to protect the motor when the set output current is exceeded.
thermal
(Thermal time constant can be adjusted 0.5 to 75.0min.)
A PTC thermistor stops the drive to protect the motor.
PTC thermistor
Warning signal can be output based on the preset level before stopping the drive.
Overload early
warning
Stall
Lowers output frequency to prevent overcurrent trip when output current exceeds the limit value during
acceleration, deceleration, or constant speed operation.
Retry function
When the motor is tripped and stopped, this function automatically reset the tripping state and restarts
operation.
(Waiting time before resetting and the number of retry times can be set.)

Shall be free from corrosive gases, flammable gases, oil mist, dust, and direct sunlight. (Pollution degree 2)
