Application Information
1. Torque Control & Output Current Control
1) By amplifying the voltage difference between Ec and Ecr from Servo IC, the Torque Sense AMP produces the input
(V
AMP
) for the Current Sense AMP.
2) The output current (I
O
) is converted into the voltage (V
CS
) through the sense resistor (R
CS
) and compared with the V
AMP
.
By the negative feedback loop, the sensed output voltage, VCS is equal to the input V
AMP
. Therefore, the output current
(I
O
) is linearly controlled by the input V
AMP
.
3) As a result, the signals, E
C
and E
CR
can control the velocity of the Motor by controlling the output current (I
O
) of the
Driver.
4) The range of the torque voltage is as shown below.
