Application ‘3’: Presets
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 as per the Truth Table below:
DX2 (Preset Select 1) DX3 (Preset Select 2)
DI4 (Preset Select 3)

The keypad can be used to re-define the speed levels of the PRESET 1 to PRESET 7 setpoints. Reverse
direction is achieved by entering a negative speed setpoint.
