ANSWER:
You have changed one or more dynamization times of cams on the FM352 using the "Fast Cam" function. Afterwards dynamization is no longer correct. Even the dynamization of cams whose dynamization times have not been changed is possibly incorrect.
The problem occurs only when you change the dynamization times of cams 16 to 127, not however with cams 0 to 15.

Problem description:

• The dynamization time of a cam 16 to 127 is changed during operation to a smaller or the same time value.
• The dynamization time of this cam was previously the greatest dynamization time of all the parameterized cams.
• After change, the dynamization is incorrect.

Problem solution:

• With cams 0 to 15 any one cam with any cam start, any cam end and any track specification is parameterized with a dynamization time.
• The dynamization time is greater than the dynamization time entered in each case with "Change Fast Cam".
• This auxiliary cam must also be set to "Valid". You can disable its switching function by setting "none" as effective direction.
  The disadvantage here is that the speed measuring cycle of the module is always based on the dynamization time of the auxiliary cam.
• Even without auxiliary cams, changing the dynamization time a second time leads to subsequent correct dynamization. For this you must call the "Change Fast Cam" function twice with identical parameters.
