Motors are not moving, because no current will be set due to some wrong parameters.
|
|
But the servoloop is running and gives output:
|
|
ServoOut set value from 0.5099 to -0.5099 (= MaxPosErr*Kp) when moving at different position
|
|
Motor[1].Servo.MaxPosErr=1000.0169
|
|
Motor[1].Servo.Kp=0.000512
|
|
1000.0169*0.000512=0.5120086528
|
|
|
|
Motor[1].Servo.Kp=0.0007
|
|
Motor[1].Servo.MaxPosErr=1000.0169
|
|
1000.0169*0.0007=0.70001183
|
|
|
|
Now some elements have to be reconfigured:
|
|
SlipGain,PwmSf,PhaseMode,PhaseCtrl,PhasePosSf
|
|
|
|
|
|
Motor[1].pPhaseEnc = PowerBrick[0].Chan[0].PhaseCapt.a //is default

|
|
move one pole (13mm)
|
|
Read PowerBrick[0].Chan[0].PhaseCapt 166599808
|
|
difference = 166599808-130559= 166469249

|
|

|
|
PhasePosSf= 2048./166469249 = 1.2303e-05 or precise: 2048/(256*650000)=1.23077e-05
