• If no limit characteristic curve is saved, an equivalent characteristic is shown. It is represented as a red
dotted line ( ).
 Maximum operating point
 Continuous rated curve
• Limit characteristic curve for the torque which the motor can provide continuously (S1 operation) with-
out overheating.
 Rated point of the motor
 Torque-speed characteristic of the application requirement
• For checking the motor-inverter combination the characteristic always has to be below the characteristic
curve.
 Rated motor speed
 Performance features
• The performance features can also be found in the selection table. Selection table ( 319)
