Problem: cPro random connection shutdown
Partially solved (see below)
I hope you guys can help me! I contacted cMotion, but they are already on vacation.
unfortunately we had a horrible shoot yesterday because my CPro One connection kept shutting down irregularly.
My 1AC and I couldn't really pinpoint the problem.
Symptoms:
Lens Data was suddenly gone, but focus could still be adjusted, zoom no longer, no camera control either.
After a very helpful phone call with cmotion support I can say that we had at least two issues parallel maybe even three. 1. the data license was not installed correctly. This was due to a coding change in the license file I received. It is possible to install this file “half”, so the manual says to check this in the “About” menu of the cPro after installation. A downgrade to 5.0 may help, or a rewritten file containing all the other files. I managed to install it eventually by trying 7 times on 6.02.
2. loss of contact to a motor leads to the assumption that either the LBUS socket of the cPro or the cForce is broken. It often occurs on older models that do not have the new upgraded “movable” socket. Do not use L-shaped elbow cables. This is the reason why cMotion does not sell them!
(3.) Even 2 motors at 14.4V 10A can be very current hungry during calibration or fast runs. Always use two current inputs at both ends of the chain.
