Ensure DIP switch A2 is place d to I (current).
□ Switching between Main /Auxiliary Frequency Command
If either of analog input terminal A1 or A2 is set to 3 ( Auxiliary Frequency Command), the
multi-speed step 1 will follow analog input frequency command, for more detail please
refer to table 6.12.“Multi-Step Speed Command and Multi-Function Terminal
Combinations”
2 : Terminal UP/DOWN
Use digital input terminals S1 to S7 to increase or decrease the frequency.
3 : Modbus Communication
Allows frequency command via the Modbus communication. Make sure RS-485/422 serial
communications port is connected to control circuit terminals J1 and J4. Refer to “Modbus
Communication” for instructions.
4 : Pulse Train Input (Including PWM Signal Input)
Allows frequency command from pulse train input terminal RP
