Is it possible to scale Altivar 320 analog input to have precisely 25.0Hz when input AI1=5V?
Issue:
Customer needs to scale analog input to have 5V equal 25Hz speed.
Product line:
Altivar 320, ATV320 Altivar Machine
Environment:
All models
Cause:
n/a
Resolution:
By default, the analog input on the Altivar 320 follows Low speed to High speed range in menu Inputs/Outputs CFG > Reference Template = Standard
To have the drive to follow 25Hz with 5V analog signal, set LSP to 0.0 and HSP to 50Hz. Otherwise 5V cannot refer to 25Hz.
If necessary, adjust AI1 min value, AI1 max value, AI1 range, AI1 Internal points X or Y.
