Overvoltage Specification
200 V class: Stops when DC bus voltage exceeds approximately 410 V
400 V class: Stops when DC bus voltage exceeds approximately 820 V
Low Voltage Protection
Drive stops when DC bus voltage falls below the levels indicated:
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
Stops after 15 ms
Heatsink Overheat
Protection
Protected by thermistor
Braking Resistor Overheat
Protection
Overheat input signal for braking resistor (Optional ERF-type, 3% ED)
Stall Prevention
During acceleration and during run: Separate settings for each type of stall prevention
determine the current level at which stall prevention is triggered.
During deceleration: Select, enable/disable.
Cooling Fan Failure
Protection
Circuit protection (“fan-lock” sensor)
Ground Fault Protection
Electronic circuit protection
