Servo On and Off with MC_Power

MC_Power is used to power on a single servo axis. When Enable is ‘TRUE’, the servo will be powered on. When Enable is ‘FALSE’, the servo will be powered off.

  • Axis input must be a variable with the value of the axis to be controlled.

  • LS_Connect must be executed before this function block can be used to control an axis.

  • The following examples can be found in the XMC_SingleAxis_FBs.zip downloadable from Example Applications.

Element Name Element Type Description
Enable Input Level detected request to execute the function block.
Axis Input/Output Axis reference variable.This can not be a constant.
Status Output Indicates the status of axis power.
Valid Output Indicates the validity of motion function block output.
Error Output Indicates whether an error occurs or not.
ErrorID Output Error Identification number.

//Set Axis 1 reference

Axis1 := 1;

//Example MC_Power FB. Check that axis is ready

IF (_AX01_RDY) THEN

INST_MC_POWER(Enable:=Enable_Power,Axis:=Axis1,

ErrorID=>INST_MC_POWER.ErrorID);

END_IF;
