AS motor

There are two methods of creating a motor data set for the asynchronous motor.

• Variant 1: Motor calculation
• Variant 2: Motor identification.htm

Calculation:

• Enter motor data
  The motor data relevant to the calculation must be entered from the data sheet.
• Click the "calculation" button.
  
• If the moment of inertia of the motor P 0461 Mot_J is not known, a value roughly corresponding to the motor's moment of inertia must be applied.
• The calculation process be observed on the DriveManager 5 by choosing the View, Messages menu.
• Calculation of operating point:
  Flux P 0462 MOT_FluxNom, P 0340 CON_FM_Imag.
• Calculation of: current, speed and position control parameters
  
  
  
  

ATTENTION All existing motor parameters are overwritten.

Calculated values

• Flux settings (including for torque constant)
• Control settings for current controller:
  
  The current controller is dimensioned dependent on the switching frequency setting.
• Speed controller and position controller gain:
  
  In this, a moderately rigid mechanism and a 1:1 moment of inertia adjustment from the load to the motor are to be assumed.
• V/F characteristic
