I have a client who wants to use an ODE-3 drive for pump pressure control.He wants to use 2 fix setpoints, lets say 30% and 15% for the pressure setpoint. Is there a way to provide this?

Yes, it’s possible.

–          Use analog input 1 as setpoint, P-44 = 1

–          Set the Analog Input Offset P-39 = -100.0%

–          Set the Analog Input Scaling = 15.0%

–          Connect the analog input as a digital input, switching either from terminal 1 (24V) or terminal 5 (10V)

This works by using the scaled output from the analog input to the setpoint. You can see the setpoint % in P00-01

By connecting a switch, we apply either 0% or 100% to the analog input.

Analog Result = (Input% – P-39) x P-35

Therefore, with 0% input, result is 0 – (-100%) x 15% = 15%

With 100% input, result is 100% – (-100%) x 15% = 30%
