Note:
• Set H3-02, H3-10 = 3 [AI1 Function Selection, AI2 Function Selection = Freq Ref/BIAS] to set AI1 and AI2 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 AI3 as an analog input (voltage/current) terminal. The default setting for DIP switch S4 is
"AI".

Set MFAI Terminal AI3 to PTC Input

Set terminal AI3 as an MFAI or as the PTC input for motor overload protection.
Use DIP switch S4 to set the input function.

Settings
AI Functions as an MFAI terminal.
(Default) Set H3-06 [AI3 Function Selection] to select the input function.
AI3
Functions as the PTC input terminal.
PTC Set H3-06 = 16 [AI3 Function Selection = Mot PTC Input].
Set S1-3 to "V" for voltage input.

Set Output Signals for MFAO Terminals AO1, AO2

Set the signal type for terminals AO1 and AO2 to voltage or current output. Use jumper switch S5 and H4-07
[AO1 Signal Level Select], H4-08 [AO2 Signal Level Select] to set the signal type.
