Chapter 3
Functional Description

Similarly, the External Velocity Ref (Parameter 154) has been linked to
source Parameter 301. The 16 bit output word for group 2 of rack 2 must
be a 16 bit signed integer whose value corresponds to the allowable values
in drive units for Parameter 154.

Information from the drive consists of Logic Status (Parameter 100) and
Velocity Fdbk (Parameter 106). Based on the links shown in Figure 3.2, the
16 bit input word for group 1, rack 2 in the PLC Controller is a 16 bit logic
status word. The bits in this 16 bit word are defined by the description for
Parameter 100. In addition, the 16 bit input for group 2, rack 2 in the PLC
Controller is a 16 bit signed integer whose value corresponds to the
allowable values in drive units for Parameter 106.
