Input Data Format
The correct format for the Network Input Data when the SMD23E2 or SMD24E2 is in Command Mode is
shown below.
Table R6.20 Network Input Data Format: Command Mode
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 Configuration
Word 1 Format , bit 9 starting on page 65.) 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
Data Format on page 69 for an explanation of this format. When the
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.
Status Word 0 Format
Figure R6.4 Command Mode: Status Word 0 Format
Bit 15: Mode_Flag –
Set to “1” if in Configuration Mode, and set to “0” if in Command Mode.
Bit 14: Module_OK –
“1” when the SMD23E2 or SMD24E2 is operating without a fault, “0” when an
internal fault condition exists.
