Hello,
I'm using an ax1500 with encoder module and cannot seem to set a max speed. I change the time base, and the same RPM results... the only apparent control over speed I have is changing the 50% voltage setting, or changing the battery itself (not preferred).
Also, my analog input (penny and giles joystick) has only a few degrees of travel before reaching max speed... its slightly better in linear mode than exponential strong or weak, which doesn't seem to make much sense... it reads fine on the test run in Roborun, but the power swings to full in very little travel.
Thanks for any advice.

You should be able to use the time base in the encoder setting to set a maximum speed, unless you already have that time base value set to max.
If you know your PPR, enter it in the encoder screen. Different time base will give you the max speed that the motor will be allow to reach at that time base value. Make sure the controller is configured in closed loop speed mode.

Thanks. I'm already at 64. Any way to increase? (slow motors down?) |

Unfortunately not. See if there is a way for you to send more pulses per turn. You may consider mounting an encoder. |
