Set up using AMC AB15A100 drives, brushed DC motor Prototrak Plus with Encoders

Many thanks, andypugh!!

I will be checking the 2 small transformers for voltage over the weekend.

Many thanks for your time.

Edit: There are 2 transformers, 1 is 5.6 v DC; the other 1 is burnt out, it was 24 v DC, went to TB-2. I plan to try the other 5.6 v DC transformer to both TB-1 & TB-2.

Many thanks, I am very greatful for the help!!

Over the weekend, I used the 5.6 v DC transformer (power supply to TB-1) & then, used a 12 v rechargeable battery to supply power to TB-2. The same error message appears both times, "5i25.0.7i77.0.1.analogoutout0-scalemax not found". To be clear, TB-5, pins 1 & 2 are not connected to anything, yet. I have ordered replacement 24v DC transformer.

Many, many thanks for helping, all suggestions are warmly welcomed.

Without LinuxCNC running, open a terminal.

halrun
loadrt hostmot2
loadrt hm2_pci
show pin
exit

Copy and paste the output here.

andypugh, Many thanks!! The file is attached/inserted.  

It hasn't found the 7i77. The most likely explanation is that field power is not being supplied to the IO board section.

andypugh, thank you for your help!! A new 24 v DC power supply will arrive this weekend, around the 14th. The A-M-C engineer is traveling early this week.

Many thanks for all the help & suggestions.
