The MC_MoveZeroPosition (High-speed Home) instruction is also provided to perform positioning to
home as defined for this method.
The MC Function Module can operate the motor even when home is undefined (excluding
MC_MoveZeroPosition).
Additional Information
Software limits are not valid when home is not defined.
Changes in the home definition status for operations and events are listed in the following table.
Name
Description
High-speed Homing
The axis returns to home using an absolute position of 0 as the target position.
Function
Operation
Jogging and velocity control
If home is not defined, the position at startup is defined as 0 to control movement.
High-speed homing
High-speed homing cannot be used.
If it is used, an instruction error will occur.
Positioning
If home is not defined, the position at startup is defined as 0 to control movement.
Interrupt feeding
Starting cam operation
Starting gear operation
Synchronous positioning
Combining axes
Torque control
Zone monitoring
Linear interpolation
Interpolation cannot be used.
If it is used, an instruction error will occur.
Circular interpolation
Operation or event
Condition for change
Home definition status
change
Servo turned ON or axis

Incremental encoder
No change
When absolute data is read normally from the
absolute encoder
Home is defined.
When absolute data cannot be read from the
absolute encoder
Home is undefined.
Changing the current position When starting
Home is undefined.
Homing
When starting
Home is undefined.
When ending
Home is defined.
Overflows and underflows
When overflow or underflow occurs
Home is undefined.
