Asynchronous motor (ASM)¶
ASM control in scalar mode (no feedback)¶
| Parameter | Description |
|---|---|
| D-Mode | 20 = U/f control mode |
| M-Inull | nominal current, i²t is calculated for each phase, if exceeded it falls to error |
| M-polepairs | number of motor poles |
| M-CommutationSource | 10 = ASM mode |
| M-Un | ASM nominal voltage |
| IM-fn | nominal/synchronous frequency |
| IM-Umin_u_f | minimum control voltage U/f , to increase torque at low speed |
| IM-Umax_u_f | maximum voltage at U/f control, to limit motor power. The peak voltage is equal to the DCbus voltage only the effective value is limited. |
Asynchronous motor control is enabled via PG as in synchronous motor modes. However, no position or speed control is used here. The PG output in this case is a synchronous frequency.
Vector control (with Hiperface DSL sensor)¶
| Parameter | Description |
|---|---|
| M-CommutationSource | 10 = ASM mode |
| IM-Rs | stator resistance |
| IM-Ls | Stator Inductance = Lsσ + Lm |
| IM-Rr | Rotor Resistance |
| IM-Lr | Rotor inductance = Lrσ + Lm |
| IM-Lm | Magnetizing inductance |
| IM-Id_rms | nominal excitation current Id (rms value) |
Motor control is possible in all modes as with a synchronous motor.
Gear¶
This functionality allows the implementation of an electronic transmission and an electronic cam.
Note
The electronic cam is in continuous development and has not been implemented yet.
Electronic transmission via input position and gear ratio and determines the position of the motor. Replaces less efficient mechanical gearboxes.
