Protection Design
<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, 4A0052ooA, and 4A0065 to 4A0590.
<7> Drive models 2A0011 to 2A0273 and 4A0011 to 4A0302 are designed to IP20 NEMA 1, UL Type 1 specifications with a protective cover on the
top. Removing this top protective cover voids the NEMA 1, UL Type 1 protection while maintaining IP20 conformity; removing the bottom conduit
bracket voids the NEMA 1,UL Type 1 protection and IP20 conformity.

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 (18 °F) [5 °C (9 °F) for 2A0273 and 4A0124] of the outside
air temperature.
2. Ambient temperature range for continuous operations is -10 °C to +40 °C (14 °F to 104
°F) when external heatsink installation method is applied for models 2A0343 and
2A0396 and 4A0361 to 4A0590.
