10.1
Supported Drive assembly objects
The DeviceNet specification includes a series of pre-defined assembly objects for
different devices, including Drives, and the SI-DeviceNet supports several of these pre-
defined assembly objects. The format of the DeviceNet pre-defined assembly objects is
fixed.
Table 10.1 Pre-defined SI-DeviceNet assembly objects
To select a pre-defined input or output assembly object:
1. Specify the input assembly object required in Pr
S.01.018
.
2. Specify the output assembly object required in Pr
S.01.019
.
3. Set Pr
MM.007
to On to reset the SI-DeviceNet, and make the changes take effect.
10.1.1 Basic speed control
Output assembly object 20
The scanner must be configured for 4 Tx bytes (or 2 Tx words) if this output assembly
object is selected.
The basic control word uses a full 16-bit word, with the bits having functions as shown
below.
