Phase Compensation with MC_Phasing

MC_Phasing performs a master position phase shift for the slave axis. The slave axis will be in Synchronous Control state. Phase correction can be executed again during a previously running phase correction command.

MC_Phasing provides a way to smoothly apply a master offset to a slave axis without directly modifying the master axis. MC_Phasing is commonly used along with MC_TouchProbe for performing position corrections on the slave axis in a registration application. LS_Connect and MC_Power/MC_PowerAll must be executed before these function blocks can be used.

The examples in this topic can be found in the XMC_MultiAxis_FBs.zip downloadable from Example Applications.

Element Name	Element Type	Description
Execute	Input	Edge detected request to execute the function block.
Master	Input/Output	Select the master axis for the phase correction. This must be a UINT variable with a value of the master axis number.
Slave	Input/Output	Select the slave axis for the phase correction. This must be a UINT variable with a value of the slave axis number.
Phase Shift	Input	Specify the phase compensation distance.
Velocity	Input	Specify the operation speed.
Acceleration	Input	Specify the acceleration.
Deceleration	Input	Specify the deceleration.
Jerk	Input	Specify the change rate of acceleration/deceleration.
Done	Output	Indicates the phase compensation distance was reached.
Busy	Output	Indicates the execution of the function block.
Active	Output	Indicates the function block is controlling the relevant axis.
CommandAborted	Output	Indicates the function block command was aborted.
Error	Output	Indicates an error occurred during the execution of the function block.
ErrorID	Output	Error Identification value.
CoveredPhaseShift	Output	Continuously outputs the compensation amount while the phase compensation is being executed.
