Frequency Reference6- 7Inputting the Frequency Reference Using Control Circuit Terminal (Analog Setting)When b1-01 is set to 1, you can input the frequency reference from control circuit terminal A1 (voltage input),control circuit terminal A2 (voltage or current input)Inputting Master Speed Frequency Reference Only (Voltage Input)When inputting a voltage for the master speed frequency reference, input the voltage to control circuit termi-nal A1.Fig 6.4 Voltage Input for Master Speed Frequency ReferenceInputting Master Speed Frequency Reference Only (Current Input)When inputting a current for the master speed frequency reference, input the current to control circuit terminalA2, input 0 V to terminal A1, set H3-08 (Multi-function analog input terminal A2 signal level selection) to 2(current input), and set H3-09 (Multi-function analog input terminal A2 function selection) to 0 (add to termi-nal A1).Fig 6.5 Current Input for Master Speed Frequency ReferenceSwitch between 2 Step Speeds: Master/Auxiliary SpeedsWhen switching between the master and auxiliary speeds, input the master speed frequency reference to con-trol circuit terminal A1 and the auxiliary speed frequency reference to control circuit terminal A2 . Themaster speed frequency reference input to terminal A1 will be used for the Inverter frequency reference whenthe master speed reference 1 allocated to multi-function input terminal (factory setting: S5) is OFF, and theIMPORTANTTurn ON pin 2 of DIP switch S1 (toward I), the voltage/current switch, when inputting a current to terminal A2.Turn OFF pin 2 of DIP switch S1 (toward V), the voltage/current switch, when inputting a voltage to terminalA2.
