Torque derating as a function of the motor speed

Derating of motor output torque as a function of motor speed (with daisy chain)

With daisy chain connection, the motor output torque should be reduced when the motor

speed is below 1500 rpm.

Torque derating of 2KJ8 asynchronous motor

Torque derating of 2KJ8 synchronous reluctance motor

Derating of motor output torque as a function of motor speed (without daisy chain)

For motors with speed range 1:5 or 1:8.7, if the converter is not connected via daisy chain,

the motor torque should be reduced when the motor speed is below 600 rpm. For motors

with speed range 1:10 and without daisy chain connection, the motor can be operated at its

rated torque until 300 rpm.
