over current
over current
(OP)
I have a press unit wth 3 motors and 3 vfds. The control panel is reading over current and press 2 is not working. Its a very old japanese unit, the vfd for press 2 has 3 lights, (power, run, error). Only "power" is displayed on that vfd, no run, no error. When the motor and vfd are disconnected over current is still displayed. Everything else on this units works. Note this motor is controlled via a pot. No wiring diagram. Please help!
