7.3.6 Set and save reference position
If this bit has been activated and the remaining bits in the command byte have not been set, the
current position will be saved as the instrument’s new zero position. All positional data now use
this point as a reference. In order to prevent and unwanted run, no other bit can be set in the
command byte; otherwise the value will not be accepted.
For firmware version 7 and higher (parameter software: 15507), the current position transferred
in the target position module is assigned to the reference point and saved permanently.
Example: Set reference point, target position = 1000

new actual position = 1000.
7.3.7 Accept and proceed to position
This bit signals the positioning unit that a valid target value has been provided. The drive will
begin a new positioning run as soon as this bit is set (provided the release bit has been set). For
this to occur, the release bit must be set and no errors may be active.
7.3.8 Manual run, down
A manual run is started if this bit is set and the ‘accept position’ bit has not been set. The run
begins with a single increment, the length of which
can be set via the ‘jog key increment size’
parameter. The drive then waits the amount of time specified by the ‘jog key pause’ parameter;
afterwards the run continues at the speed set in the ‘manual run’ parameter until the operator
disengages the key. A manual run will not be performed if the pause is set to 0 ms, in which case
the run can only proceed in single increments.
7.3.9 Manual run, up
See 7.2.8 Manual run, down
7.4 Target position
This 32Bit Value will send the next position to be achieved in target value increments to the drive.
When activating the ‘accept and proceed to position’ bit in the control word the drive will start to
move towards this position. If the bit reamins set, the drive will follow each change of this value
immediately.
