It could be that they have provided our company with sub-bargain basement models but even that shouldn't excuse the number of motor failures, gearbox failures or even the terrible programming of the UI.
Yaskawa-Motoman, Fanuc, KUKA, Honda NES, etc. all provide a more reliable and cost-effective product when downtime is taken into consideration. How a company the size of ABB can ship what is essentially an alpha stage product to a large manufacturing site belonging to one of their primary customers is beyond any of us here.
If it wasn't for the accountants taking control I'm sure we wouldn't have been blindsided by the dishonesty of the ABB offering that our company received.
