MLFB_HomeUsingCurrentPosition

 Function Block - Homing using current position.

Inputs

Input	Data Type	Range	Unit	Default	Description
ibExecute	BOOL	FALSE, TRUE	N/A	No default	Start homing, edge-triggered.
iAxisID	DINT				ID of the axis block of the Pipe Network.
iPosition	LREAL				Reference position.

Outputs

Output	Data Type	Range	Unit	Description
obDone	BOOL	FALSE, TRUE	N/A	Done bit.
obActive	BOOL	FALSE, TRUE	N/A	Active bit.
obError	BOOL	FALSE, TRUE	N/A	Error bit.
oErrorID	DINT		N/A	Error identifier: ErrorID Description 1 Axis in error. 2 Axis is not enabled. 3 Timeout exceeded or expired. 4 SDO read/write error. 5 Input parameter out of range.

Remarks

• Use this parameter to set the value of the home position other then zero.
  • This allows you to offset your home reference away from zero.
• Using the current position is the most basic homing method.
  • This method uses the current position of the motor as the home point reference.
