10.3 Flow of Operation Following a Home Return
Home return
When is mounted in slot 0
Operation example
When the startup flag is turned ON, acceleration is carried out based on the settings, until the target
speed is reached. If near home input exists at that point, the speed slows to the startup speed, and then,
if home input exists at that point as well, the movement stops.
When Y102 is turned ON in the program above, the motor for the first axis begins to accelerate, and
continues accelerating until the target speed is reached. If there is near home input at that point, the
motor decelerates to the startup speed. After deceleration has been completed, the motor stops if home
input exists.
Data required for settings
-The following data must be written to the specified addresses of the shared memory.
-Control code can change the home return direction, home input valid logic, near home input valid logic,
with or without home search and limit input valid logic.
-Operation is determined by the following four types of data.
・Control code
・Startup speed
・Target speed
・Acceleration/deceleration time
Operation steps
Step 1: Preparatory stage
The data for operation is transferred to the shared memory ahead of time.
