208 V class: Stops when the DC bus voltage decreases to less than approximately 190 V
480 V class:
• Stops when the DC bus voltage decreases to less than approximately 350 V when you use an input voltage less than 400 V
• Stops when the DC bus voltage decreases to less than approximately 380 V when you use an input voltage less than 460 V
• Stops when the DC bus voltage decreases to less than approximately 440 V when you use an input voltage of 460 V or more

Immediately stops when power loss is 15 ms or longer.
Continues operation if power loss is shorter than 2 s (depending on parameter settings).
Momentary Power
Loss Ride-thru
Note:
Stop time may be shortened depending on the load and motor speed.
Heatsink Overheat
The drive stops when the thermistor detects an IGBT temperature more than approximately 100 °C (212 °F). The trip temperature level is different for different

drive models.
Stall prevention is available during acceleration, deceleration, and during run.

Electronic circuit protection
Note:
Ground Fault
This protection detects ground faults during run. The drive will not provide protection when:
Protection
• There is a low-resistance ground fault for the motor cable or terminal block
• Energizing the drive when there is a ground fault.
DC Bus Charge LED
Charge LED illuminates when DC bus voltage is more than 50 V.

Area of Use
Overvoltage Category III
Power Supply
IP55/UL Type 12: -10 °C to +40 °C (14 °F to 104 °F)
• When you install the drive in an enclosure, use a cooling fan or air conditioner to keep the internal air temperature in the permitted range.
Ambient Temperature
Setting
• Do not let the drive freeze.
• You can use IP55/UL Type 12 drives at a maximum of 50 °C (122 °F) when you derate the output current.
95% RH or less
Humidity
Do not let condensation form on the drive.
-20 °C to +70 °C (-4 °F to +158 °F) (short-term temperature during transportation)
Storage Temperature
Pollution degree 2 or less
Install the drive in an area without:
• Oil mist, corrosive or flammable gas, or dust
• Metal powder, oil, water, or other unwanted materials
Surrounding Area
• Radioactive materials or flammable materials, including wood
• Harmful gas or fluids
• Salt
• Direct sunlight
1000 m (3281 ft) maximum
Note:
Derate the output current by 1% for each 100 m (328 ft) to install the drive in altitudes between 1000 m to 4000 m (3281 ft to 13123 ft).
Altitude
It is not necessary to derate the rated voltage in these conditions:
• When you install the drive at 2000 m (6562 ft) or lower
• When you install the drive between 2000 m to 4000 m (6562 ft to 13123 ft) and ground the neutral point on the power supply.
• 10 Hz to 20 Hz: 1 G (9.8 m/s
Vibration
• 20 Hz to 55 Hz: 0.2 G (1.96 m/s
Installation
Install the drive vertically for sufficient airflow to cool the drive.
