(4) Automatic setting of torque bias amount with terminal 1 or terminal 6 (FR-A7AZ)
[Pr. 840 = 3, Pr. 846, C16 to C19, C34 to C37]
When [Pr. 840 = 3] while using terminal 1, [C16 to
C19(Pr. 919, 920)] and [Pr. 846] are automatically set
according to the load. When [Pr. 840 = 3] while using
terminal 6, [C34 to C37(Pr. 928, 929)] and [Pr. 846] are
automatically set according to the load. Refer to the
following diagram for the setting method.
When torque bias amount is set to terminal 1, set [Pr.
868 Terminal 1 function assignment = 6]

To set torque bias amount 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.
When starting torque bias operation after completion
of automatic setting, set 1 or 2 in [Pr. 840].
