200 V class: Stops when the DC bus voltage is more than approximately 410 V
Overvoltage
Protection
400 V class: Stops when the DC bus voltage is more than approximately 820 V
Single-phase 200 V class: Stops when the DC bus voltage decreases to less than approximately
160 V
Undervoltage Three-phase 200 V class: Stops when the DC bus voltage decreases to less than approximately
Protection 190 V
Three-phase 400 V class: Stops when the DC bus voltage decreases to less than approximately
380 V
Stops when power loss is longer than 15 ms and continues operation if power loss is shorter than
2 s (depending on parameter settings).
Momentary
Note:
Power Loss • Load size and motor speed can cause the stop time to be shorter.
Ride-thru
• Drive capacity will change the continuous operation time. A Momentary Power Loss
Recovery Unit is necessary to continue operation through a 2 s power loss on models 2001
to 2021 and 4001 to 4012.

Stall Prevention Stall prevention is available during acceleration, deceleration, and during run.
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
Charge LED illuminates when DC bus voltage is more than 50 V.
