Selects the reset function after tripping.
Upon reset, It is also possible to restart the
adjustable frequency drive.
Selecting Manual reset [0], allows a reset via

automatic reset (1-10 times) after tripping,
select data value [1]-[10].

reached within 10 minutes, the adjustable
frequency drive enters Manual reset [0]
mode. When a Manual reset is performed, the
parameter setting is back in force. If the number
of AUTOMATIC RESETs is not reached within 10
minutes, the internal AUTOMATIC RESET counter
is reset. Also, if a Manual reset is performed, the
internal AUTOMATIC RESET counter is reset.
