At least one of you good folks have more than one Okuma & Howa HL-20 and I would appreciate you contacting me again. Almost a year past since I posted about my HL-20 being beaten up severely by the shipping company, but they did pay to repair! Finally got it all together and fired it up with new battery pack, however having some issues. I did not get the list of machine builder parameters with the unit. Got everything else but need to go through the parameters and see if some have gone askew. Every time I try to home the unit it alarms out alarm 90 and doesn't know where home is. manual moves to any X-Z position yields a restart of all zero X-Y position. I just need to start looking for the bugs, Fanuc's maintenance manual for alarm 90 troubleshooting doesn't help as much as knowing the exact parameter settings will, ( I believe). Any help will be greatly appreciated! PS: using Fanuc 18t

PS 90 is caused by either you starting too close to the home switch when you start or you are travling too slow. Make sure your RAPID override is set to 100%
