General-purpose analog input
XA (0)
General-purpose analog input
XA (1)
General-purpose analog input
XA (2)
- Explanation
These variables can be used to monitor the data input to the O, OI, and O2 terminals (among the
analog input terminals of the inverter) in a data range from -100.00 to +100.00. The analog inputs
monitored with these variables correspond to the data set by the [O]-[L], [OI]-[L], and [O2]-[L] input
functions (A011 to A015, A101 to A105, and A111 to A114).
- Sample program: Program to configure output frequencies in steps of 10 Hz with general-purpose
analog inputs
