Hi everyone,
On my L32(older L4 series), I recently had a Z1 axis servo amplifier blow out - not sure why.... so I purchased and installed a refurbished one. The machine now powers up fine with no alarms, but every time I try to move the Z1 axis, the machine goes into an E-stop alarm with the servo amp display indicating codes for either overload or excessive error.
I then decided to swap servo drive units(including encoders) with another matching axis to see if the alarm traveled to the other drive. I found that after doing so, the alarm was still on the Z1 axis.
Then I decided to swap servo amplifiers with another matching axis. Again, after doing so, the alarm was still on the Z1 axis.
Now, I’m thinking it has either got to be a short in the cable which goes from the servo amplifier to the encoder OR a short in the power cable for the servo motor, right?
Should I be looking at anything else?
Any advice given would be greatly appreciated.
