Altivar 320 Adjustable Speed Control with Digital Inputs and Potentiometer

[alexmtnz]

Good afternoon, I have an Altivar 320 currently set up so that when Digital Input 1 (DI1) is activated, it starts the motor and allows control via the potentiometer with LSP = 6 Hz and MSP = 60 Hz. Now, I’ve been asked to add a function where, when Digital Input 2 (DI2) is activated, the MSP value changes to 45 Hz, allowing it to be adjustable with the potentiometer across the full range, from 6 Hz to 45 Hz. The same would apply to DI3. Any ideas? Thanks in advance.

Hi check these parameters. SH2/SH4 HSP2..4

Sorry for the german text in screenshot. But with the parameter name you will find the meaning of the parameters in the manual.

Good afternoon, Bastian. Thank you for your support. I made the change, and when I activate DI2, the VFD runs at 45 Hz, but it is not adjustable from the potentiometer. Thank you.
