Specification
Overload Protection
Drive stops when the output current is more than these overload tolerances:
•
110% of the rated output current for 60 seconds
•
140% of the rated output current for 2.5 seconds when the drive output frequency is 3 Hz
The permitted frequency of overload is one time each 10 minutes.
Note:
If output frequency < 6 Hz, the drive can trigger the overload protection function when the output current is in the overload tolerance range.
Overvoltage
Protection
208 V class: Stops when the DC bus voltage is more than approximately 410 V
480 V class: Stops when the DC bus voltage is more than approximately 820 V
Undervoltage
Protection
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
Momentary Power
Loss Ride-thru
Immediately stops when power loss is 15 ms or longer.
Continues operation if power loss is shorter than 2 s (depending on parameter settings).
Note:
Stop time may be shortened depending on the load and motor speed.
Heatsink Overheat
Protection
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
Stall prevention is available during acceleration, deceleration, and during run.
Ground Fault
Protection
Electronic circuit protection
Note:
This protection detects ground faults during run. The drive will not provide protection when:
•
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.

Ambient Temperature
Setting
IP20/UL Type 1 and IP55/UL Type 12: -10 °C to +40 °C (14 °F to 104 °F)
IP20/UL Open Type: -10°C to +50 °C (14 °F to 122 °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.
•
Do not let the drive freeze.
•
You can use IP20/UL Open Type and IP20/UL Type 1 drives at a maximum of 60 °C (140 °F) when you derate the output current.
•
You can use IP55/UL Type 12 drives at a maximum of 50 °C (122 °F) when you derate the output current.
Humidity
95% RH or less
Do not let condensation form on the drive.
Storage Temperature
-20 °C to +70 °C (-40 °F to +158 °F) (short-term temperature during transportation)
Surrounding Area
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
•
Radioactive materials or flammable materials, including wood
•
Harmful gas or fluids
•
Salt
•
Direct sunlight
Altitude
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).
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.
