- When the input signal Vin, through the pin (pin 22, 23, 24 and 25) is above the Vbias, then the motor (actuator) is in
reverse direction.
- If you want to change the gain, then modify the external resistor's value (Rextern)
3. Torque & Output Current Control
Torque Control & Output Current Control
- By amplifying the voltage difference between E
C
and E
CR
from the Servo IC, the torque sense AMP produces the input
(V
AMP
) for the current sense AMP.
- The current sense AMP produces the input for the Gain controller to allow the output current (I
O
) of the driver to be
controlled by the input voltage (V
AMP
), where the output current (I
O
) is detected by the sense resistor (R
NF
) and is
converted into V
RNF
.
- In the end, the signals of the Servo IC control the velocity of the motor by controlling the output current (I
O
) of the
driver.
- When the junction temperature rises up to about 175
°
C, then the output drive circuit will be shut down.
- The range of the torque control input voltage is as shown below.
The input range (E
C
) of the Torque Sense AMP is 0.5V ~ 3.3V
