Switch motor configuration

Hi,

I need to make the same channel on my controller control two types of motors, according to the user's choice.

For this, I created two virtual motors and a plc that makes the selection between the setups according to a Boolean flag, but it is not working.

Follow the plc:

if (homeInit == 0)

{

if (Gate3[0].Chan[0].Status & $100)

{

Motor[12].ServoCtrl = 0

Motor[12].pDac = Sys.pushm

Motor[11].ServoCtrl = 1

Motor[11].pDac = PowerBrick[0].Chan[0].Pwm[0].a

setup = 1

}

else

{

Motor[11].ServoCtrl = 0

Motor[11].pDac = Sys.pushm

Motor[12].ServoCtrl = 1

Motor[12].pDac = PowerBrick[0].Chan[0].Pwm[0].a

setup = 2

}

homeValue = Gate3[0].Chan[0].Status & $100

homeInit = 1

}

Hello,

I guess it's necessary to change the values of:

Motor[11].pAbsPhasePos

Motor[12].pAbsPhasePos

For the proper phase commutation

If the motor is a stepper without encoder, for example, you will also need to consider the changes in

Motor[11].pAbsPos

Motor[12].pAbsPos

Motor[11].pEnc

Motor[12].pEnc

Motor[11].pEnc2

Motor[12].pEnc2

Hello,

Thank you for your support.

After I did the post yesterday, I tried a few more things and managed to get Motor[2] to operate a motor allocated on channel 1 of the controller. These were the changes I made:

Motor[2].ServoCtrl = 1

Motor[2].pAbsPhasePos = PowerBrick[0].Chan[0].PhaseCapt.a

Motor[2].pDac = PowerBrick[0].Chan[0].Pwm[0].a

Motor[2].pAdc = PowerBrick[0].Chan[0].AdcAmp[0].a

Motor[2].pAmpEnable = PowerBrick[0].Chan[0].OutCtrl.a

Motor[2].pAmpFault = PowerBrick[0].Chan[0].Status.a

Motor[2].pEncCtrl = PowerBrick[0].Chan[0].OutCtrl.a

Motor[2].pEncStatus = PowerBrick[0].Chan[0].Status.a

Motor[2].pCaptFlag = PowerBrick[0].Chan[0].Status.a

Motor[2].pCaptPos = PowerBrick[0].Chan[0].HomeCapt.a

Motor[2].pPhaseEnc = PowerBrick[0].Chan[0].PhaseCapt.a

And this is my Open Loop EncTable:

EncTable[2].type = 11

EncTable[2].pEnc = Motor[2].PhasePos.a

EncTable[2].index1 = 5

EncTable[2].index2 = 0

EncTable[2].index3 = 0

EncTable[2].index4 = 0

EncTable[2].index5 = 255

EncTable[2].index6 = 1

EncTable[2].ScaleFactor = 1 / (256 * (EncTable[1].index5 + 1) * EXP2(EncTable[1].index1))

But when I try to do exactly that configuration with Motor[11] controlling channel 1 of the controller, what happens is the operation of a common virtual motor, with no real output on the controller.

If Motor 2 works, but Motor 11 (with otherwise identical settings) doesn't, what value is Sys.MaxMotors?

Is it possible that you have multiple motors writing to the same target register at the same time? If Motors 2 and 11 are both set such that Motor[x].pDac = PowerBrick[0].Chan[0].Pwm[0].a at the same time, the motors will fight one another and overwrite each other.

Just to make sure you don't have any other motors that might be conflicting, can you try to set Motor[x].ServoCtrl = 0 for all motors other than Motor 11?

Hello,

Thank you for your support.

I made sure that the Sys.MaxMotors parameter was greater than 11 (I put 50).

I added this following lines on my configuration to make sure I don't have any other motors that might be conflicting, but it's still not working:

Motor[1].pDac = Sys.pushm

Motor[1].ServoCtrl = 0

Motor[11].ServoCtrl = 1

Motor[11].pAbsPhasePos = PowerBrick[0].Chan[0].PhaseCapt.a

Motor[11].pDac = PowerBrick[0].Chan[0].Pwm[0].a

Motor[11].pAdc = PowerBrick[0].Chan[0].AdcAmp[0].a

Motor[11].pAmpEnable = PowerBrick[0].Chan[0].OutCtrl.a

Motor[11].pAmpFault = PowerBrick[0].Chan[0].Status.a

Motor[11].pEncCtrl = PowerBrick[0].Chan[0].OutCtrl.a

Motor[11].pEncStatus = PowerBrick[0].Chan[0].Status.a

Motor[11].pCaptFlag = PowerBrick[0].Chan[0].Status.a

Motor[11].pCaptPos = PowerBrick[0].Chan[0].HomeCapt.a

Motor[11].pPhaseEnc = PowerBrick[0].Chan[0].PhaseCapt.a

Hi,

I finally found the solution! I needed to add the registers below to my Motor[11] .phm file:

Motor[11].EncType = 5

Motor[11].AmpEnableBit = 8

Motor[11].LimitBits = 9

Motor[11].AmpFaultBit = 7

Motor[11].CaptControl = $14080801

Thank you all for your help!
