Overload Protection
Drive stops when the output current is more than 150% of the rated output current for 60 s.
Note:
The drive may trigger the overload protection function at 150% of the drive rated output in under 60 s if the output frequency is less than 6 Hz.
Overvoltage
Protection
200 V class: Stops when the DC bus voltage is more than approximately 410 V
400 V class: Stops when the DC bus voltage is more than approximately 820 V
Undervoltage
Protection
200 V class: Stops when the DC bus voltage decreases to less than approximately 190 V
400 V class: Stops when the DC bus voltage decreases to less than approximately 380 V
Heatsink Overheat
Protection
Thermistor
Braking Resistor
Overheat Protection
Overheat detection for braking resistor (optional ERF-type, 3% ED)
Stall Prevention
Stall prevention is available during acceleration, deceleration, and during run.
Ground Fault
Protection
Electronic circuit protection
Note:
This protection detects any 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 present.
DC Bus Charge LED Charge LED illuminates when DC bus voltage is above 50 V.

Dust: IEC60721-3-3:3S2
Power Supply
Overvoltage Category III
Ambient
Temperature
Open chassis type (IP20): -10°C to +50 °C (14 °F to 122 °F)
Enclosed wall-mounted type (UL Type 1): -10 °C to +40 °C (14 °F to 104 °F)
•
Do not use the drive in a location where the temperature changes suddenly to improve the drive reliability.
•
When installing 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.
•
Derate the output current and output voltage to install the drive in areas with ambient temperatures ≤ 60 °C (140 °F).
Humidity
95% RH or less
Do not let condensation form on the drive.
Storage Temperature -20 °C to +70 °C (-4 °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
Keep wood or other flammable materials away from the drive.
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:
•
Installing the drive at 2000 m (6562 ft.) or lower
•
Installing the drive between 2000 m to 4000 m (6562 ft. to 13123 ft.) and grounding the neutral point on the power supply.
Contact Yaskawa or your nearest sales representative when not grounding the neutral point.
