4.8.2.3 Bits in the Control Word / Status Word

The following bits in the Control Word are used for controlling positioning:
*)
Value"
The drive sets the following mode-specific bits in the status word as response:
Remarks:

m Set Value handshaking:

4 New set value
5 Change set immedi-
ately
6 Absolute / Relative Flag for deciding between absolute and relative target specification
Z118.2–
Mode Bit 11: Interpretation of control word when control is by "New Set
0: Compatible with b maXX 4400: If Bit 5 = 0, then Set Specification
1: In accordance with IEC61800-7-201: If Bit 5 = 0; then Set Value Specification
Bit Name
10 Target position

12 Set Value
handshaking
The Target Position Reached message indicates that the positioning target has been
reached. It is only displayed if the "New Set Value" control word bit is cleared. Due to
the handshake procedure, this message is not displayed if the "New Set Value" bit is
set.
An exception is the "Automatic Start after Change of Positioning Set" option (Bit 10 in
Z118.2–
Mode). In this case the Set Value Reached message is not suppressed, even
with the "New Set Value" control bit set.
Set Value handshaking is the controller's response to a new start command. The drive
sets this bit when the positioning data have been transferred and the positioning has
been started.
The drive clears the bit as soon as it is ready to accept new set values. The controller
may not start any new positioning tasks while this bit is set. In contrast, the data in the
positioning records can be changed.
Signal for transferring data and starting the positioning procedure.
Used in the handshake process.
Rising edge activates a positioning procedure
Flag for deciding between Set Specification and Set Value Specifica-
tion.
The logic depends on the interpretation set in Parameter
Mode Bit 11. *)
Set Specification: The drive should hold at the target. New motion tasks
during the positioning procedure are taken up immediately.
Set Value Specification: The drive only accepts the next motion task
once the target position is reached. It is not held in the target position.
(only if a special target mode is selected).
0: Absolute target specification
1: Relative target specification
Report that the target position has been reached.
0: Target position not reached
1: Target position reached
Handshake signal, response from the drive regarding the acceptance
of the positioning data:
0: Drive is ready to receive new set values.
1: Confirmation by the drive of acceptance of the set values.
