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 150% 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> 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.
<5> Removing the top protective cover or bottom conduit bracket from an IP20/NEMA 1, UL Type 1 enclosure drive voids NEMA 1, UL Type 1
protection while maintaining IP20 conformity. This is applicable to models 5A0003 to 5A0242.

Electronic thermal overload relay
Drive stops when rated output current exceeds 175%
Drive stops after 60 s at 110% of rated output current
Drive stops after 0.5 s at 140% of rated output current
600 V class: Stops when DC bus voltage exceeds approx. 1040 V
Immediately stop after 15 ms or longer power loss
Continuous operation during power loss shorter than 2 s by speed search function
Thermistor
Stall Prevention is available during acceleration, deceleration, and during run.
