12.2 b: APPLICATION
Use and on the keypad to change the frequency reference.
1 : Analog Input
Use MFAI terminals AI1, AI2, and AI3 to input an analog frequency reference with a voltage or current input
signal.
• Voltage Input
Refer to Table 12.5 to use a voltage signal input to one of the MFAI terminals.
Terminal Signal

AI1 0 - 10 V
-10 - +10 V
AI2 0 - 10 V
-10 - +10 V
AI3 0 - 10 V
-10 - +10 V
