virtual master axis generator is activated by writing the value "1" to
the direct
variable "DV_P_0_0917". Afterwards, the operation mode "phase synchroni‐
zation" is activated for the punching drive via the function block "fbGearInPo‐
sAxis1" by setting the variable "bExeGearInPos". Simultaneously, the position‐
ing of the virtual master axis is started via the function block
"fbMoveAbsVmAxis" by setting the variable "bExeAbsVmAxis" to the initial po‐
sition of the master axis for material feed (rVmInitPos: REAL: = 0.0;). When the
function block "fbGearInPosAxis1", via the "InSync" output, signals that the
punching drive has synchronized and the function block "fbMoveAbsVmAxis"
additionally signals via the "Done" output that the initial position of the master
axis for material feed has been reached, the operation mode "electronic motion
profile" is activated for the roll drive via the function block "fbMotionProfilAx‐
is2" by setting the variable "bExeMoProfil". When this function block, too,
signals via the "InSync" output that it has synchronized, switching to step 4
takes place.
Step 4 (iContinuousMotion): Continuous operation
Fig.7-19: Code Section 2.1.4
After both axes have been aligned with one another, the actual application op‐
eration can start. For application operation, the virtual master axis is only moved
continuously. For this purpose, the function block "fbMoveVelocityVmAxis" is
activated by setting the variable "bExeVelVmAxis".
