îš„Inputting Torque References and Torque Reference Directions
The torque reference can be changed according to an analog input by setting H3-09 (Multi-function analog
input terminal A2 selection) or H3-05 (Multi-function analog input terminal A3 selection) to 13 (torque refer-
ence) or 14 (torque compensation). The torque reference input methods are listed in the following table.

Between A3 and AC
H3-04 = 1
H3-05 = 13
Set H3-04 to 0 for a 0 to 10-V torque ref-
erence.
To switch the torque reference between
positive and negative torque, set a multi-
function analog input to 78.
Between A2 and AC
(Turn OFF pin 2 of
SW1.)
H3-08 = 1
H3-09 = 13
Set H3-08 to 0 for a 0 to 10-V torque ref-
erence.
To switch the torque reference between
positive and negative torque, set a multi-
function analog input to 78.
The input can be used for torque compen-
sation by setting H3-09 to 14.
