Description
Axis technology object
Start of the task with a positive edge
Mode = 0, 2, and 3 (Absolute position of axis after
•
completion of the homing operation)
Mode = 1 (Correction value for the current axis position)
•
Limit values: -1.0e
≤ Position ≤ 1.0e

Homing mode
0: Direct homing absolute
•
New axis position is the position value of parameter
"Position".
1: Direct homing relative
•
New axis position is the current axis position + position
value of parameter "Position".
2: Passive homing
•
Homing according to the axis configuration. Following
homing, the value of parameter "Position" is set as the
new axis position.
3: Active homing
•
Reference point approach in accordance with the axis
configuration. Following homing, the value of parameter
"Position" is set as the new axis position.
TRUE = Task completed
TRUE = The task is being executed.
TRUE = During execution the task was aborted by another
task.
TRUE = An error has occurred during execution of the task.
The cause of the error can be found in parameters "ErrorID"
and "ErrorInfo".
Error ID for parameter "Error""
