7 Setup
7.3.2 Related Parameters
For the initial setup when using MBA405W, the following parameters are required to be set in addition to those related to
the DC excitation function. If the initial setup for MBA405W is performed before setting these parameters, an alarm for
Initial parameter error (37) occurs.
【#2321】 SV121 Kpp Magnetic pole detection position loop gain
Set this parameter to adjust the motor magnetic pole position and encoder's installation phase at
using MBA405W.
Set the position loop gain in the magnetic polar detection loop at the initial magnetic polar detection.
The initial magnetic polar detection is performed for the direct-drive motor which uses MBA405W as
the motor side encoder.
Related parameters : SV122,SV123,SV124
--- Setting range---
0 to 32767
【#2322】 SV122 Kvp Magnetic pole detection speed loop gain
Set this parameter to adjust the motor magnetic pole position and encoder's installation phase at
initial setup when using MBA405W.
Set the speed loop gain in the magnetic polar detection loop at the initial magnetic polar detection.
The initial magnetic polar detection is performed for the direct-drive motor which uses MBA405W as
the motor side encoder.
Related parameters : SV121,SV123,SV124
--- Setting range---
0 to 32767
【#2323】 SV123 Kvi Magnetic pole detection speed loop lead compensation
Set this parameter to adjust the motor magnetic pole position and encoder's installation phase at
initial setup when using MBA405W.
Set the speed loop lead compensation in the magnetic polar detection loop at the initial magnetic
polar detection.
The initial magnetic polar detection is performed for the direct-drive motor which uses MBA405W as
the motor side encoder.
Related parameters : SV121,SV122,SV124
--- Setting range---
0 to 32767
【#2324】 SV124 ILMTmp Initial magnetic polar estimate/current limit value
Set this parameter to adjust the motor magnetic pole position and encoder's installation phase at
initial setup when using MBA405W.
Set the current (torque) limit value in the magnetic polar detection loop at the initial magnetic polar
detection.
The initial magnetic polar detection is performed for the direct-drive motor which uses MBA405W as
the motor side encoder.
When set to "0", use SV014(ILMTsp) for the current limit at the initial magnetic polar estimate.
Related parameters : SV121,SV122,SV123
--- Setting range---
0 to 200
