6.1.5.2 Use of controlword and statusword
The cyclic synchronous position mode uses no mode specific bits of the controlword and
three bits of the statusword for mode-specific purposes. Figure 64 shows the structure of the
statusword. Table 236 defines the values for bit 10, 12, and 13 of the statusword.

6.1.5.3 Detailed object definitions
6.1.5.3.1 Object 60B0
h
: Position offset
This object shall provide the offset of the target position. The offset shall be given in user-
defined position units.
NOTE The value itself is absolute and thus independent of how often it is transmitted over the
communication system, for example, transmitted twice does not mean double value. Since the
additive position value represents an offset to the target position it can be also used to control
the drive with relative values with regard to the target position.
