Torque Command to be reported. The default mode and offset for User Selected
Data 1 can be set in the module configuration software.
4.21 Select Return Data 2. This command allows alternate data to be reported in the User
Selected Data 2 %AI location for each axis. The alternate data includes information
such as Parameter memory contents and the DSM314 Firmware Revision.
The Select Return Data 2 command uses a mode selection and an offset selection.
The mode selection (byte offset +1 of the six-byte command) determines the Return
Data type. The offset selection (byte offsets +2, +3 of six-byte command) selects an
individual data item for some modes. Setting the mode to 00h causes the default
Torque Command to be reported. The default mode and offset for User Selected
Data 2 can be set in the module configuration software.
The following selections are allowed for Select Return Data 1 and Select Return
Data 2.
