Once a reference value has been transmitted to the drive, the controller signals a
permissible value in the control word
by a rising signal edge for the bit “New reference
value”.
The drive responds by setting the bit “Reference value confirmed” and starts
moving to the new target position. After that, the controller resets the bit “New refe
ence value”, and the drive reset
s the bit “Reference value confirmed”. Once the bit
“Reference value confirmed” has been reset, the drive is ready for receiving a new
target position.
