I’m currently attempting to repair a Ryco Monarch II. The gantry would not respond to any inputs at the manual positioning controller, so I replaced the VF Drive (FR-Z024-1.5K-UL). After replacement I can drive the gantry forward but not back, rotate arm one direction but not the other, and trolly will not respond. I can hear the contacts engaging but gantry does not respond. I cannot track down any service/parts manuals online so if anyone can point me in the right direction it would be great appreciated. This machine is needing a lot of general parts replaced and love.
