0x451 - Homing offset
This object indicates the configured difference between the zero position for the application and the machine home position, as found during the homing process.
During homing, the machine home position is found and once the homing is completed, the zero position is offset from the home position by adding the home offset to the home position.
A negative value indicates opposite direction.
If the desired 0 position is located 2000 counts to the positive direction when the homing is done, the homing configuration needed is:
Homing mode → X
Homing offset → 2000
Once the actuator finish the homing procedure at the homing location, the actual position value will be 2000.
