I have two Sumitomo AF502-3A7 drives on a cylindrical grinder. Both are hooked up the same way. The drives mount on the back of the machine and are controlled by two boxes in the front. The drives can be programmed to work off their panels or remotely, which I am doing. One does exactly what the manual says, start is controlled by the forward run line and speed is by a pot with 12 volts DC across it.
The change from panel to remote is changed by Code 4 set to 0 or 1. One drive shifts start and speed as the manual says. The other moves the start to remote but not speed. I can change speed on that one by the up/down arrows when it is set for panel control but not in remote. The speed control voltage is varying with the pot setting, so there is no failure there. The manual also says that code 35 changes panel key functions from panel to remote. It is locked on 1 on both drives, when I enter a 0 they change back. The information may be in the manual, but it is not indexed and I have to find things by reading through a lot of unrelated information to find it. I only found the code 4 function by a footnote in tiny print.
Any suggestions?
