Parameter
Menu 9
structure
Menu 9 contains 2 logic block functions (which can be used to produce any type of 2 input logic gate, with or without a delay), a motorized pot function
and a binary sum block. One menu 9 or one menu 12 function is executed every 4ms. Therefore the sample time of these functions is 4ms x number
of menu 9 and 12 functions active. The logic functions are active if one or both the sources are routed to a valid parameter. The other functions are
active if the output destination is routed to a valid unprotected parameter.

Indicates the level of the motorized pot prior to scaling. If Pr 9.21 is set to 0 or 2 this parameter is set to 0 at power-up, otherwise it retains its value at
the last power-down.
