Protection Design
<1> Overload protection may be triggered when operating with 150% of the rated output current if the output frequency is less than 6 Hz.
<2> Actual specifications may vary depending on motor characteristics.
<3> Use a separate Momentary Power Loss Ride-Thru Unit if the application needs to continue running for up to 2 s during momentary power loss.
<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.

Thermal overload relay
Drive stops when output current reaches about 200% of the rated current
Drive stops after 60 s at 120% of rated output current
208 V: Stops when input voltage exceeds approx. 315 V
480 V: Stops when input voltage exceeds approx. 630 V
208 V: Stops when input voltage falls below approx. 150 V
480 V: Stops when input voltage falls below approx. 300 V
Immediately stop after 2 ms or longer power loss
Continuous operation during power loss than 2 s (standard)
Stall Prevention is available during acceleration, deceleration, and during run.
