Alarm Reset

When the inverter trips, remove the cause then
press the PRG/RESET key on the keypad panel
or input a reset command from the RST control
terminal to reset the tripping state. Because the
reset command is activated by an edge, supply
the command in an OFF - ON - OFF sequence
as shown in Fig. 6-2-1.
When resetting the tripping state, deactivate the
operation command. If the operation command
is left turned on, the inverter starts operation
immediately after the error is reset.
