Is is possible to scale ATV320 analog input to have precisely 25.0Hz when AI1=5V

Published date: 25 February 2019

Issue:
Need to scale 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 ATV320 follows Low speed to High speed in Inputs/Outputs CFG > Reference Template = Standard

To have the drive 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 Interim points X or Y. 

See the extracted pages from the ATV320 programming manual attached
