Yes, Reliance and also Electro-Craft, they were I think swallowed up by Allen Bradley who are now part of Rockwell Automation. If you see reliance or ElectroCraft drives be careful as there are ones that predated the DDM drives, think they are just DM and they are analogue only. I have a few of them but badged Osai who were also once part of Allen Bradley, they are a PITA drives as you need to get a motor and drive matched, there is a personality chip you can get programmed to match the motor but obviously that costs and when I was testing them out it just suddenly died and the module was wiped, was going to cost me £50 plus to get it reprogrammed but luckily the DSA drives turned up so I gave up with the step/dir to analogue idea
I bought a 25m reel of cable for around £50 I think from RS components and made all the cables up, I bought a load of the 45pin connectors for the drive from a place in the UK called Rapid, they had a clearance on and I think they were 10p each so the cables ended up quite cheap. For the power cables I bought some SY cable from eBay.
