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.

Ambient Temperature
Setting
• 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.
• You can use IP20/UL Open Type drives at a maximum of 60 °C (140 °F) when you derate the output current.
• You can use IP20/UL Type 1 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.
Storage Temperature -20 °C to +70 °C (-4 °F to +158 °F) (short-term temperature during transportation)
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:
• 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.
• 10 Hz to 20 Hz: 1 G (9.8 m/s
• 20 Hz to 55 Hz:
Vibration
2004 to 2211, 4002 to 4168: 0.6 G (5.9 m/s
2257 to 2415, 4208 to 4720: 0.2 G (2.0 m/s
Installation Install the drive vertically for sufficient airflow to cool the drive.
