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 volt-
age(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
. The output current (I
O
) is lin-
early controlled by the input V
AMP
.
3) 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.
