Ask you, a CJ1G-CPU42H problem CJ1G-CPU42H that occasionally there will be a normal (5% probability), there are three motor to test the remaining two not thought the encoder connection problem, can eliminate driving and connecting line, after the welding connection is still the same encoder directly an Sichuan servo motor electric alarm AC9

If the nosaid OMRON CJ1G-CPU42H encoder OMRON CJ1G-CPU42H is good, the probability is so low, there are several possible 1: motor encoder end outlet is connected in the motor encoder 2: off line is reliable, is loose 3: encoder component whether weld 4: whether shielding problems, interference (I have met)
