● 0: no combination
● 1: first frequency setting + second frequency setting
● 2: first frequency setting - second frequency setting EFC 3600 has two frequency setting sources: the first frequency setting source [b1.00] and the second frequency setting source [b1.16]. It is allowed to use any of the frequency command sources or the combination of them.
● When the combination of two sources is active: The reference and calculation of each part of the combination follows the rules and definitions when it is used as a single command source input. Each part of the combination has the full frequency range, which means that the combined frequency may theoretically become smaller than 0.00 Hz (when [b1.15] is set to 2]) or larger than [b1.06] (when [b1.15] is set to 1). So the combined frequency is limited to the range of 0.00 Hz ~ [b1.06].
