Example of "Free telegram" commissioning
1. Drive commissioned with T352 and change then parameter 922 Telegram Type
set to [999] for use with Free Telegram
Figure 5-15
2. Check r2067 in the Expert List. All words being sent to the drive from the PLC
and from the PLC to the drive must be accounted for. Vector Speed uses 6 words
IN / 6 words OUT. That message frame must agree with r2067 in the Expert List.
Figure 5-16 Example using T352 AOI for Free Telegram before terminating spare words
3. Words not being used must be terminated to "Dummy Parameters". These
words could be used for more useful connections such as Added Speed Setpoint,
Torque Limits, or Torque Setpoints. This programming can be done via scripting,
Expert List, or the Starter GUI.

a Standard Telegram or making a User Defined Telegram.
