The point that is specific to a machine and serves as the reference of the
machine is referred to as the machine zero point. A machine tool builder
sets a machine zero point for each machine.
A coordinate system with a machine zero point set as its origin is referred
to as a machine coordinate system.
A machine coordinate system is set by performing manual reference
position return after power–on (see V–3.1). A machine coordinate
system, once set, remains unchanged until the power is turned off.
When manual reference position return is performed after power–on, a
machine coordinate system is set so that the reference position is at the
coordinate values of (
α, β) set using parameter No.1240.
