(3) Setting torque bias amount with terminal 1 or terminal 6 (FR-A7AZ)
[Pr. 840 = 1, 2, Pr. 846 to 848, C16 to C19, C34 to C37]
Calculate torque bias from the load input to terminal 1
or terminal 6 (FR-A7AZ) as shown below and multiply
by the torque bias.
When torque bias amount is set to terminal 1, set [Pr.
868 Terminal 1 function assignment = 6]
When torque bias amount is set to terminal 6 (FR-
A7AZ), set [Pr. 406 High resolution analog input

selection = 6]. When [Pr. 406 = 6] and [Pr. 868 = 6],
terminal 6 is the torque bias, and terminal 1 does not
have a function.
