Limit switch functions Slowdown and stop limit inputs for both directions

Speed control range s

... 100% (s

= motor nominal slip)

Speed accuracy 1% of nominal speed at speed range 10 ... 100%

1/3 of motor nominal slip at speed below 10%

Extended speed range 100 ... 200%

Braking torque 150%

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

Ambient conditions

Ambient temperature

-10°C ... +55°C (14°F ... 131°F) for ED≤60%

Storage temperature

-40°C ... +60°C (-31°F ... 140°F) dry

Humidity <95%RH (no condensation)

Altitude Maximum 1000m at In. Above 1000m: In reduces 1% per each 100m.

Above 3000m: consult factory.

Vibration Operation: maximum displacement amplitude 3mm at 2-9Hz.
