How Home Works
The Home is used in applications in which the axis must be precisely aligned with some part
of the machine. The Home is initiated in one of three ways: with the Initiate Destination
function found in the Assignments view, through a program, or with the Online tab. A Home
or Define Home is required to set the Absolute Position Valid so that any index to absolute
position can work.
The FM-3 module can home the motor to an external sensor, the motor’s encoder marker
pulse, or to a sensor and then to the encoder marker pulse.
