Setting the Torque Reference, Speed Limit, and Torque Compensation Values
Torque Control Input Value Selection
Table 11.44 lists the method for torque control input signals.
Configuration Parameter
Torque Reference
Speed Limit
Torque Compensation
*1 Sets analog input terminals A1, A2, and A3 to supply the speed limit, torque reference, or torque compensation. If you set the same
function to A1 to A3 terminals with H3-02, H3-10, or H3-06, the drive will detect oPE07 [Analog Input Selection Error].
Input Signal Polarity
The positive and negative torque references set the motor rotation direction. The direction of the Run command
does not set it. The positive and negative torque reference signals and the direction of the Run command have an
effect on the internal torque reference.

Notes
The level of the set input signal
must align with the polarity of
the external signals.
H3-02, H3-10, or H3-06 settings
are enabled for the option card
input terminal. The level of the
set input signal must align with
the polarity of the external
signals.

The drive applies the settings in
C1-01 to C1-08 [Acceleration/
Deceleration Times] and C2-01
to C2-04 [S-Curve Time @ Start/
End of Accel/Decel] to the speed
limit.

The level of the set input signal
must align with the polarity of
the external signals.
H3-02, H3-10, or H3-06 settings
are enabled for the option card
input terminal. The level of the
set input signal must align with
the polarity of the external
signals.
