Stepper Motor Max Speed and Acceleration

Apologies if this has been discussed previously, but just a quick one to ask if it should be possible to increase the maximum stepper motor speed and acceleration beyond 2000 steps/sec and 10000 steps/sec/sec? Whenever I try and type in numbers greater than these it just returns back to these numbers. I saw in the stepper motor introduction video that the maximum speed was increased beyond this, so I'm guessing the controller is capable of delivering a higher frequency output? It would be useful to do this for me to speed up the response as I have ended up with a driver with a minimum steps per revolution of 400, rather than 200. 

Thanks very much.

I should add that I am aware that having the maximum speed too fast could result in the motor missing steps, but mine has not reached that threshold yet and also has an encoder that acts as an input into the driver to warn if steps have been missed. 

Thanks again.

Hi,

2000 steps/sec is the max today. It is lower than the theoretical max to decrease the load on the YourDyno processor. Are you able to swap to a motor with 200 steps/rev? Then you get a full 10 revs/sec with 2000 steps/sec. Another idea is a different gearing. 

The acceleration can be increased, there is no load associated with that, it was just a number I expected would be high enough for all applications. If you swap to 200 steps/sec then I bet you it is enough, but let me know otherwise.

Hi,

Thanks for getting back to me. In that case I will look into getting a driver that will go down to 200 steps per revolution. 

Thanks again.
