Amplifier Fault ECT60 Closed Loop

Again, please clarify which drive you ended up taking. Because a closed-loop drive is sold by the seller at a slightly higher price. This is probably due to the low-level firmware. They might have sent you a cheaper version.

As per the first post this is an ET60 so it has encoder inputs and associated firmware. The ECR60 is open loop only.
I wonder if you would be so kind as to share your working config?

how did you get the ECR moving in the first place? did you add the lcec_rtec.c to the lcec_main.c ? I'm a bit stuck and out of ideas

Hi rodw

I was observing the same behaviour on my ect86. It works in open loop but stutters and outputs an amplifier fault in closed loop mode. The lights on the driver indicate an encoder out of tolerance alarm. In the same thread someone else also reported the same issue. Unfortunately I never figured it out.

Strange, my ECT86 machine was perfect from day 1 out of the box. And another user the same. I have 2 closed loop and one open loop on it. I think I better get the config off the machine and compare it with this, I don't trust what I have saved.... I will share it.

So after throwing my ethercat stuff in the corner in disgust for six months or so ago, I pulled it out and finally fixed it!

I reset the drive to factory defaults by adding this into my xml filePowered up Linuxcnc, homed the drive and tried to move it which sounded awful, then unplugged the power supply to the ECT60 ethercat drive.
Closed Linuxcnc and deleted that code from the XML file.

Hey presto running as smooth as a baby's bum!

The manual says 
Sub-index of object dictionary 0x1011: 01 Write 1, and then power on again to restore the driver to the factory state. When restoring the factory setting, first stop the motor running, then save the parameters. Thats roughly what I did!
