Input Data Format

The correct format for the Network Input Data when the SMD23E2 or SMD24E2 is in Command Mode is
shown below.

Format of Position Data Values

The format of the Motor Position, Encoder Position, and Trapped Encoder Position values is controlled by the
Binary_Input_Format bit in the configuration data written to the Networked Driver. (See
Word 1 Format, bit 9 starting on page 63.) When the Binary_Input_Format bit equals "0", the position val-
ues are reported with the bottom three digits of the value in the lower word (000 - 999) and the remaining dig-
its in the upper word. See
Binary_Input_Format bit equals "1", the position values are reported as 32-bit signed integers, with the 
location of the least significant bit determined by the Binary_Endian bit in the Configuration data.
The range of values when using the multi-word format is -32,768,000 to 32,767,999. When
used in continuous rotation applications, such as control of a conveyor belt, it is possible to
overflow these values. When any of the three position values overflow, the value of the associ-
ated data words will become indeterminate. AMCI strongly suggests using the signed 32-bit
integer format for continuous rotation applications.
