Optimization of S120 driven induction motor

When S120 drives ordinary induction motors (SIEMENS motors or third-party motors) using vector mode (VECTOR) or encoder free vector mode (SLVC). The optimization steps are as follows:

1.1 Proper motor configuration

a) Complete project configuration

b) Enter the rated data of the motor according to the motor nameplate

c) If you know the relevant mechanical data input motor moment of inertia P341, system moment of inertia to motor moment of inertia ratio P342, motor weight P344

d) The equivalent diagram data of the motor does not need to be input

e) Set the frequency converter working mode P1300, load type P205, and process application P500

Equivalent circuit diagram of induction motor:

Perform motor optimization after project configuration is completed

Motor optimization conditions: The motor is in a cold state, the brake is not closed, and effective measures are taken to ensure that the mechanical system is not dangerous
