Current control / limiting on Simple Motor Controllers?


A question regarding the Simple Motor Controllers, e.g. the 18v25:
When RC servo-style signal is used as input, is possible to configure the device so that output current is limited to a fixed value? When the current limit is exceeded, the output PWM duty cylce should be reduced, but not shut off completely.
Best Regards, Nils



The Simple Motor controller does not have a feature to set the current limit. Instead, you might consider the jrk 12v12 or one of the Roboclaw motor controllers. Both have a current limit that can be set by the user. I recommend looking through the user’s guide for each to see if they would be suitable for your application.
