Function
Once the controller requests homing, the ADI4 transmits the actual encoder value to the
controller as the home position the next time it detects an encoder zero mark.
Without 611U conformant mode
No further measures are required.
With 611U conformant mode
The relevant signal for the axis to be homed (e.g. Axis 1) must be set in the digital output word:
• Digital output word:
Bit 0: = 0 ⇒ "Axis 1: Zero mark of Encoder 1 (X4-1)"
