card, on the gate drive card, or the ribbon cable between
the power card and gate drive card.
WARNING/ALARM 40, Overload of digital output ter-
minal 27
Check the load connected to terminal 27 or remove
shortcircuit connection. Check 5-00 Digital I/O Mode and
5-01 Terminal 27 Mode.
WARNING/ALARM 40, Overload of digital output ter-
minal 29
Check the load connected to terminal 27 or remove
shortcircuit connection. Check 5-00 Digital I/O Mode and
