Environment
Area of Use Indoors
Ambient Temperature
-10 °C to +40 °C (14 to 104 °F) IP20/NEMA Type 1 Enclosure, External Heatsink (2A0011 to 2A0273
and 4A0005 to 4A0302)
-10 °C to +50 °C (14 to 122 °F) IP00/Open Type Enclosure (2A0343 and 2A0396, and 4A0361 to 4A0590)
Note: 1. To install a heatsink on the outside of a panel, design the panel to keep the air temperature
inside the panel within 10 °C (5 °C for 2A0273 and 4A0124) of the outside air
temperature.
2. Ambient temperature range for continuous operations is -10 to +40 °C (14 to 104 °F)
when external heatsink installation method is applied for models 2A0343 and 2A0396
and 4A0361 to 4A0590.
Humidity 95% RH or less (no condensation)
Storage Temperature -20 °C to +70 °C (-4 to +158 °F) (short-term temperature during transportation)
Altitude
Up to 1000 meters without derating, up to 3000 m with output current and voltage derating. Refer to
Altitude Derating on page 46 for details.
Vibration/Shock
10 to 20 Hz at 9.8 m/s 2
20 to 55 Hz at 5.9 m/s 2 (2A0011 to 2A0031 and 4A0005 to 4A0027) or
2.0 m/s 2 (2A0046 to 2A0396 and 4A0034 to 4A0590)
Standards IEC/EN 61800-5-1
Protection Design IP00/Open Type enclosure, IP20/NEMA Type 1 enclosure <7>
<1> The accuracy of these values depends on motor characteristics, ambient conditions, and drive settings. Specifications may vary with different motors
and with changing motor temperature. Contact Yaskawa for consultation.
<2> Overload protection may be triggered when operating with 100% of the rated output current if the output frequency is less than 6 Hz.
<3> May be shorter due to load conditions and motor speed.
<4> A 24 V power supply Unit (Model Nos. PS-A10LB, PS-A10HB) is required for models 2A0011 to 2A0059 and 4A0005 to 4A0052 if the application
must continue running for up to 2 seconds during a momentary power loss.
<5> Ground protection cannot be provided when the impedance of the ground fault path is too low, or when the drive is powered up while a ground
fault is present at the output.
<6> Setting L8-09 to 1 enables ground fault detection in models 2A0075 to 2A0396 and 4A0052 to 4A0590.
<7> Drive models 2A0011 to 2A0273 and 4A0011 to 4A0302 are designed to IP20/NEMA Type 1 specifications with a protective cover on the top.
Removing this top protective cover voids the NEMA Type 1 protection while maintaining IP20 conformity; removing the bottom conduit bracket
voids the NEMA Type 1 protection and IP20 conformity.
