Variable name
General-purpose analog output
YA (0)
General-purpose analog output
YA (1)
General-purpose analog output
YA (2)
(AMI terminal)
- Explanation
These variables can be used to monitor the data output to the FM, AM, and AMI terminals (analog
output terminals of the inverter) in a data range from 0% to 100.00%. To obtain the analog outputs, you
must assign general-purpose output functions to the FM, AM, and AMI terminals with inverter
parameters "C027", "C028", and "C029".
YA (0): FM output terminal
YA (1): AM output terminal
YA (2): AMI output terminal
- Sample program: Program to output inverter output frequency data to a general-purpose analog
output as data that is one-half of the full-scale data
