Hi Rick,
There are several jrk models. Can you specify which you have (and provide a porduct code if it is sold on the RobotShop website; RB-Pol-XX). Thanks.
Hi Rick,
The manufacturer suggests the following:
“There might be an error preventing the Jrk from driving the motor; check the Errors tab in the configuration utility. If you are trying to use a feedback mode, make sure that you have entered some non-zero PID constants (good starting values are Proportional=1, Integral=0, Derivative=0) and make sure there is a large difference between the values of the Target and Feedback variables. If you are trying to use the no-feedback (speed control) mode, then make sure that the target is not close to 2048 (speed 0); try setting the target to 2648 (full speed forward). In either case, you should look at the graph and make sure that the Duty Cycle is not close to 0; try to get it closer to +600 or -600 (full speed forward or full speed reverse).”
You may also want to reinstall the drivers and configuration utility. If the problem persists, the manufacturer would like you to contact them directly either via their forum or by email.
Hope this helps,
