The problem I have is that after the ramp generator frequency is always zero, even though at the beginning I have a frequency nonzero. I have enabled all ratings, as shown in Fig. Thank you very much for the help Attachment Ramp.jpg (73 Downloads)

So temporarily disable this by setting P845 = 1. If you look closely at the graphic (I can also just make it out on your first image you sent), even when all the "LED's" are lit, the switch is still in the OFF (0) position, this generally means that there is an internal bit that is inhibiting the start command. I have highlighted this with a Yellow Oval. If you take a look at the "Drive Enables" in the Control/Status Word section under the Diagnostics menu, this will tell you what is still missing when you are trying to run.

In addition to your comments, I realized that the signal from the potentiometer connected to the analog input of the CU320, ranged far is oscilacón was not perceived on my PC, but if it was perceived in the MOP panel. This did not allow the output frequency of the filter. I appreciate your help.
