Goals and Symptoms

Question 1 - I want to perfom +/- speed with ATV31 via keys on display, and there are some points to confirm. Page 33 ( Complete Manual_EN )-> Show us that we can get access to UPdt and UPdH sub-parameters on the Fr1 or Fr2 parameters, but I do not have access on Fr1 parameter to these sub-parameters, just Fr2. Is it correct? Question 2 After doing the program ( +/- speed) we must go to Display Menu, rFr paramenter that allows to change the reference and speed. The problem is when I power-off the drive and power-up again, even lock the Display menu at rFr parameter, I must return to display menu and rFr parameter to do same procedure. Is it correct? I have an OEM that dont want to do these procedure after doing all programs in their machines. Best regards

Causes and Fixes

Question 1:

It's possibe to have UPdt and UPdH on FR1 if you disable the sum function on AI2 and AI3 ( page 42 of programming manual ).

Question 2:

It's correct but not simple to use it and not normal. It must possible th have +/- speed without SUP menu access. Corrective action transmit for software evolution.
