PARAMETERS
4.21 Frequency/torque setting by analog input (terminal 1, 2, 4)
4.21.1 Function assignment of analog input terminal (Pr. 858, Pr. 868)
⋅ For the terminal 1 and terminal 4 used for analog input, frequency (speed) command, magnetic flux command,
torque command, etc. can be selected.
Functions change according to the control mode as in the table below.
Terminal 1 function according to control
Terminal 4 function according to control
⎯ :No function
* This setting is valid under vector control.
