vector control
2.12.1 Bias and gain of torque (magnetic flux) setting voltage (current)
[Pr. 241, C16 to C19 (Pr. 919, 920), C34 to C37 (Pr. 928, 929), C38 to C41 (Pr. 932,
933)]
(A700)
You can set the magnitude (slope) of the torque as desired
in relation to the torque setting signal (0 to 5VDC, 0 to 10V
or 4 to 20mA).
Set [
Pr. 73, Pr. 267
] to switch between 0 to 5VDC, 0 to
10VDC and 4 to 20mA. (Refer to page 217)
In the initial setting status, terminal 1 and terminal 4 used
for analog input are respectively set to speed setting
auxiliary (speed limit auxiliary) and speed command
(speed limit). To use an analog input terminal as torque
command, torque limit, and magnetic flux input, set [
Pr. 868
Terminal 1 function assignment ] and [ Pr. 858 Terminal 4
function assignment ] to change functions. (Refer to page 46)
Magnetic flux is valid only during vector control.
To use terminal 6 of FR-A7AZ for torque command or
torque limit, set [ Pr. 406 High resolution analog input selection ]
and change the function. (Refer to page 46)
