Protections
Stall prevention During acceleration and constant speed
Motor overload protection Thermistor based temperature measurement
Overload protection Fault is detected if the current momentarily exceeds 280% of rated current
Undervoltage / blown fuse Fault is detected if DC voltage drops below 333V
Overvoltage protection Fault is detected if DC voltage exceeds 911V
Momentary power loss Immediate fault stop
Inverter overtemperature Temperature sensor on the heat sink
Mechanical brake Circuit breaker
Braking transistor Electronic supervision for the braking chopper and for the braking resistor
Ground fault Provided by electronic circuitry
Overspeed / stall,
Speed difference supervision Independent measurement using sensor bearing, pulse wheel or encoder
