When this flag is set the preset timer for auto preset timer mode (Pr
01.15
= 9) is reset and preset 1 is selected. This can be used to start a new
sequence of reference selection by a programmable input terminal or function. When this bit is zero the preset selection will follow the timer even
when the drive is disabled.
