Overvoltage Specification
200 V Class: Stops when DC bus voltage exceeds approx. 410 V
400 V Class: Stops when DC bus voltage exceeds approx. 820 V
Low Voltage Protection
Drive stops when DC bus voltage falls below the levels indicated:
<5>
190 V (3-phase 200 V), 160 V (single-phase 200 V), 380 V (3-phase
400 V), 350 V (3-phase 380 V)
Momentary Power Loss Ride-
Thru
3 selections available: Ride-Thru disabled (stops after 15 ms), time base
of 0.5 s, and continue running as long as the drive control board is
powered up.

Heatsink Overheat Protection Protected by thermistor
Braking Resistor Overheat
Protection
Overheat input signal for braking resistor (Optional ERF-type, 3% ED)
Stall Prevention
Stall prevention is available during acceleration, deceleration, and
during run. Separate settings for each type of stall prevention determine
the current level at which stall prevention is triggered.
Cooling Fan Failure Protection Circuit protection (“fan-lock” sensor)
Ground Fault Protection Electronic circuit protection
