Application 3: Preset Speeds
This is ideal for applications requiring multiple discrete speed levels.
The setpoint is selected from either the sum of the analogue inputs, (as in Application 1 and known here as PRESET 0), or
as one of up to seven other pre-defined speed levels. These are selected using DIN2, DIN3 and DIN4, refer to the Truth
Table below.
