Parameter Frequency/torque setting by analog input (terminals 1, 2 and 4)
FR-A700 EC 6 - 369
6.20 Frequency/torque setting by analog input (terminals 1,
2 and 4)
6.20.1 Function assignment of analog input terminal (Pr. 858, Pr. 868)
Function assignment of terminal 1 and terminal 4 of analog input can be selected and changed
by parameter.
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 shown in the tables on the next page.
