Timing Scheme
Switching from inverter operation to commercial-power operation ISW50/ISW60: ON OFF
(1) The inverter output is shut OFF immediately (Power gate IGBT OFF)
(2) The inverter primary circuit SW52-1 and the inverter secondary side SW52-2 are turned OFF immediately.
(3) If a run command is present after an elapse of t1 (0.2 sec + time specified by H13), the commercial power
circuit SW88 is turned ON.
