Current input
Note:
• Set H3-02, H3-10 = 0 [Terminal A1 Function Selection, Terminal A2 Function Selection = Frequency Reference] to set A1 and A2 to
frequency reference. The drive will add the analog input values together to make the frequency reference.
• Use tweezers or a jig with a tip width of approximately 0.8 mm (0.03 in) to set DIP switches.
• Set DIP switch S4 to "AI" to use terminal A3 as an analog input (voltage/current) terminal. The default setting for DIP switch S4 is "AI".

Set Output Signals for MFAO Terminals FM, AM

Set the signal type for terminals AM and FM to voltage or current output. Use jumper switch S5 and H4-07, H4-08
[Terminal FM Signal Level Select, Terminal AM Signal Level Select] to set the signal type.
