Chapter 4 Explanation of Functions 4.2.11 External analog input setting (O, OI, and O2) The inverter has the following three types of external analog input terminals: O-L terminal: 0 to 10 V OI-L terminal: 4 to 20 mA O2-L terminal: -10 to 10 V Related code A005: [AT] selection A006: [O2] selection C001 to C008: Terminal [1] to [8] functions The table below lists the settings of the external analog input terminals. Item [AT] selection [O2] selection Function code A005 A006 Data Description 00 Switching between the O and OI Turning on the AT terminal enables the OI-L terminal. terminals with the AT terminal Turning on the AT terminal enables the O-L terminal. 01 Switching between the O and O2 Turning on the AT terminal enables the O2-L terminal. terminals with the AT terminal Turning on the AT terminal enables the O-L terminal. (02) (Valid only when the OPE-SR is used) Switching between the O terminal and the control with the AT terminal Turning on the AT terminal enables the pot on OPE-SR terminal. Turning on the AT terminal enables the O-L terminal. (03) (Valid only when the OPE-SR is used) Switching between the OI terminal and the control with the AT terminal Turning on the AT terminal enables the pot on OPE-SR terminal. Turning on the AT terminal enables the OI-L terminal. (Valid only when the OPE-SR is used) Turning on the AT terminal enables the pot on (04) Switching between the O2 terminal OPE-SR terminal. and the control with the AT terminal Turning on the AT terminal enables the O2-L terminal. 00 Using the O2 terminal independently 01 Using the O2 terminal for auxiliary frequency command (nonreversible) in addition to the O and OI terminals 02 Using the O2 terminal for auxiliary frequency command (reversible) in addition to the O and OI terminals 03 Disabling the O2 terminal Note that whether frequency commands are input to the O2-L terminal and whether the motor operation is reversible depend on the combination of settings of functions "A005" and "A006" and whether function "16" (AT) is assigned to an intelligent input terminal as shown in the table below. When the motor operation is reversible, the inverter operates the motor in a reverse direction if the sum of the frequencies specified by the main frequency and auxiliary frequency commands is less than 0 (even when the forward operation [FW] terminal is on). Even when no wire is connected to the 02 terminal, reverse operation of the motor may occur and prolong the acceleration time if the output voltage fluctuates near 0 V. When the AT function is assigned to an intelligent input terminal When the AT function is not assigned to any intelligent input terminal A006 A005 AT terminal Main frequency command Whether to input an auxiliary frequency command (via the O2-L terminal) Reversible/ nonreversible 00,03 00 OFF O-L terminal No input ON OI-L terminal No input Nonreversible 01 OFF O-L terminal No input ON O2-L terminal No input Reversible 00 OFF O-L terminal Input (Example 1) ON OI-L terminal Input Nonreversible 01 OFF O-L terminal Input 01 ON O2-L terminal No input Reversible 00 OFF O-L terminal Input (Example 2) ON OI-L terminal Input 02 Reversible OFF O-L terminal Input 01 ON O2-L terminal No input 00 - - O2-L terminal No input Reversible 01 - - Addition of signals on O-L and OI-L terminals Input Nonreversible 02 - - Addition of signals on O-L and OI-L terminals Input Reversible 03 - - Addition of signals on O-L and OI-L terminals No input Nonreversible 4 - 12

A001: Frequency source setting A076: PV source setting To use the operation result as the actual frequency command, specify "10" for the frequency source setting (A001). To use the operation result as the PID feedback data, specify "10" for the PV source setting (A076). Item Function code Data Description 00 Digital operator (A020/A220/A320) (01) Control on the digital operator (Valid only when the OPE-SR is connected) 02 Input via the O terminal Operation-target frequency A141/A142 03 Input via the OI terminal selection 1 and 2 04 Input via the RS485 terminal 05 Input from option board 1 06 Input from option board 2 07 Input of pulse train 00 Addition: (A141) + (A142) A143 01 Subtraction: (A141) - (A142) Operator selection for frequency operation 02 Multiplication: (A141) x (A142) Frequency source setting A001 10 Output of operation result PV source setting A076 10 Output of operation result Note 1: The [1] (up) and [2] (down) keys of the digital operator are ineffective when the frequency operation function is enabled. Also, the frequency displayed by the output frequency monitoring (d001), Scaled output frequency monitoring (d007), or output frequency setting (F001) cannot be changed with key operations. Note 2: The settings of "A141" and "A142" can be the same. 4 - 13
