Calculate the reference torque
1.1
Speed controller (Chapter 6.3 )
The PI speed controller gives the torque to regulate the speed difference between set and ac-
tual speed.
• Variable proportional factor ( Chapter 6.3.3)
• Variable proportional/integral factor (speed) (Chapter 6.3.4 )
• Determination of the mass moment of inertia (Chapter 6.3.6 )
• Speed controller PT1 output filter (Chapter 6.3.7 )
• Torque precontrol (Chapter 6.3.8 )
1.2
The maximum possible torque is reduced in the field weakening. A limitation of the set torque
is required in order to bring the drive not into voltage limit.
• Torque limiting characteristic (Chapter 6.2.10.4 )
1.3
Calculation of the max. torque limit in consideration of maximum currents and detected motor
data (Ld, Lq, Ψ)
• Adaption (Chapter 6.2.12 )
• Torque limiting characteristic (Chapter 6.2.10.4 )
• Current (Chapter 6.2.8 )
• Torque limits (Chapter 6.4 )

Precontrol of the current controller
• Current control (Chapter 6.2.6 )
3.4
Voltage limitation
• Maximum voltage (Chapter 6.2.10.3 )
3.5
Actual values current controller
• Measurement / model currents (Chapter 6.2.7 )
