Parameter Descriptions
NOTE
The motor may start without warning. If the specified
number of AUTOMATIC RESETs is reached within 10 minutes,
the frequency converter enters Manual reset [0] mode. After
the Manual reset is performed, the setting of 14-20 Reset
Mode reverts to the original selection. If the number of
automatic resets is not reached within 10 minutes, or when a
Manual reset is performed, the internal AUTOMATIC RESET
counter returns to zero.
NOTE
Automatic reset will also be active for resetting safe stop
function in firmware version < 4.3x.
