The following example demonstrates the setup of a CANopen drive for operation in Cyclic Synchronous Position mode. 

program
  
  bus[0].ctim=4000
  call can_reset ' reset can controller
' NMT PREOP state  
  bus[0].phase = 0
  sleep 300
'----------------------- IS setup -------------------------
  ax1.dadd = 1 ' drive address is "1"
  call Axis_Setup(ax1)
' NMT OP state
  bus[0].phase = 4
  sleep 100
  call CAN_SDO_WRITE(ax1.dadd,0x6060,0,8,8)' cyclic sync  position mode
  Print "Opmode =",CAN_SDO_READ(Ax1.dadd,0x6061,0) 
end program


sub Axis_Setup(Ax as generic axis)

  attach Ax  
  Ax.en=0
  Ax.pedel=5

  call CAN_SDO_WRITE(Ax.dadd , 0x60c2, 1 , 8 , bus[0].ctim/1000) '''Drive cycle time
  call CAN_SDO_WRITE(Ax.dadd , 0x60c2, 2 , 8 , -3) '''msecs
  CALL  IntergratedStepperMapPDO(Ax.dadd) ' map PDOs
  Ax.MotionBusVelocityBase=1000 
  Ax.MotionBusVelocityScale=0 

  Ax.pfac = 4096 ' one motor revolution is 4096 counts of position command (object 0x607a.0)
  Ax.vfac = Ax.pfac / 1000/60 'velicity is RPM
  Ax.afac = Ax.vfac / 1000 
  Ax.jfac = Ax.afac / 1000 
  Ax.pemax = 10
  Ax.Amax=100000
  Ax.dmax=100000
  Ax.jmax=1000000
  Ax.Acc=100000
  Ax.dec=100000
  Ax.jerk=1000000
'reset fault
  call CAN_SDO_WRITE(Ax.dadd, 0x6040, 0,16, 128)
  sleep 20
  call CAN_SDO_WRITE(Ax.dadd, 0x6040, 0,16, 0)
  detach Ax

end sub
