High Torque AX 12 in endless turn

HI,


How to achieve a high torque with low speed of AX 12 in endless turn. I found that a high speed, the torque is high, as compared to the low speed the torque is really small. I had set the max torque and torque limit at 1023. I assume the speed control is using the voltage proportional, but not PWM.. If this is the problem, how can I use a PWM method to control the speed in endless turn.


regards,


taufik

Hi Taufik,

 

Haven’t heard from you in a while too!

 

In wheel mode, you can only control the output and not the speed.

For example, if it is set to 512, maximum output is being controlled at 50%.

Thus, you can not have low speed and high torque. L

When in actuator mode, it reads the current position. So, even if the speed is low and the actual motor is not moving,

you can have high torque and control the speed.

Thanks for your reply, does it mean I can use PWM to control the output in endless/wheel turn mode, then read the motor speed to update the error, so that I can implement control gain?

Taufik,

 

You can only control the output using PWM in Endless mode.

Current position can not be read in Endless mode, so you are unable to know the current speed nor control it.

Control the speed is able possible in “Actuator Mode”
