I’m using the Generic Linear Actuator (4" Stroke, 12V, 1.5) with the Jrk 21v3. I want to use the serial command pololu protocol to drive the jrk with an arduino.
Till now everything is working fine (Motor On/Off, set target, …).
Now I have 2 questions to go on:
I want to change the speed of the linear acturator during runtime. I haven’t found any command for this. I can change the Max. duty cycle at the Plololu Jrk Configuration Utility from 600% to e.g.300% to reduce the speed. But I would like to do it during runtime with the serial interface (from arduino).
Is there any possibility?
I want to monitor the 12V supply voltage. I am think of using LiPo’s for the power supply. So it would be good to know the actual voltage. It is possible to read internal variables from the jrk over the serial command like the actual position. But I havent found some informations about the power supply. Is there an internal variable I can read?
Thanks in advance
and best regards
