Important: If you select binary format, both words are represented as
2’s-complement integers compatible with the PLC-5. See Appendix H for
examples of these words.
Local Velocity
The local velocity word defines the velocity you want for the corresponding
setpoint move. You can disable the local velocity by setting it to zero; the
module will then use the global velocity.
