2.8 H: Terminal Functions
406 YASKAWA TOEPYAIGA8002B GA800 Drive Programming
Drives have three analog input terminals, terminals A1, A2, and A3. H3 parameters select the functions set to these
analog input terminals and adjust signal levels.
Table 2.64 shows the functions that you can set to analog input terminals. Use H3-02, H3-06, and H3-10 [MFAI
Function Selection] to set functions.
