14 HF injektion
In order that these functions can be used, the following special requirements apply to the synchronous motor:
- The difference between Ld and Lq (minimum and maximum value ) should be greater than 30%.
- The curve of inductance with a circulation of rho should be sinusoidal.
These criteria can be checked during the identification (dr.48 = 2) by recording dr.31 and EC.40.
dS.30 rotor position detection
0 = off
dS.31 rotor position mode
0 : Ld different Lq
1 : Ld = Lq
The more favorable operating mode is preset by the motor identification and Fr10.
dS.32 KI HF detection
Illustration of nn.16 in dS parameters
This parameter is used to optimize the first operating mode dS.31 = 0
dS.33 current limit for HF supply
This parameter is preset by Fr10 after a motor identification.
The voltage jump is adjusted by way that the preset current is approximately reached.
This parameter must be increased if the rotor position at dS.31 = 1 is suboptimal.
The current is internally limited to maximum In.01 rated inverter current. For this the inductance in dr.31 must
be correctly measured or adjusted.
