LIP FACTOR

, A

DDRESS

Slip factor defined the ratio :

Speed

synchronous



Speed

synchronous

Standard value=1..7%, usually, 4% is a good value.

OSINUS PHI

, A

DDRESS

11.

The cosinus phi is given from the manufacture, usually, a value between 0.8 and 0.9.

2.1

Field weakening

IELD WEAKENING SPEED

, A

DDRESS

55.

If field weakening is needed, this parameter must be set to the speed value the field weakening
must begin.

2.2

Asynchronous alarm

Asynchronous overspeed, set when the motor speed is higher than 133% of synchronous
speed (only if field weakening is disabled).
