[NSRCA-dist1] Disabling slow start feature in JR WV servos

[Ed Alt]

I'll try a few simple tests and may end up throwing it on the serial bus analyzer to see what's up with it all.  I just didn't want to spend time on it, I was hoping to start putting my Allure together instead of reverse engineering JR stuff again.  The thing is, if the MP servos don't store settings, and if certain behaviors like slow startup can be controlled via XBus, that seems to imply that there is a brief PWM "handshake" prior to commencement of normal operation to change those settings.  I'm guessing that there is no capability at all to change settings in the MP's, stored or not.

In the case of a PWM servo, I do not believe it stores any information.  The NX series of "smart" servos definitely retain their programming....so once programmed, the programming remains whether they are used with XBus or PWM.

Thanks Joon.



For any JR XBus savvy folks:



There seems to be only scarce info on XBus devices.  I've got an XG14, and I'm sure I could "program a servo", but from what I gather so far, it may not be programming the servo itself, rather it is programming the XBUS device that the servo connects to.  In other words, the servo itself doesn't store any settings.  Is that correct?



Thanks Ed

Ed, I'm not a JR guy but I'm pretty sure you do it in the servo screen of an XG radio.  I believe for the radio to configure the servo, the servo has to be in the XBUS of the receiver.



As far as I know JR does not make any kind of external configurator like Hyperion or other manufacturers have for their servos.



Hope that helps !

Hello



Does anyone have the instructions on how to disable the slow start feature in the JR WV servo series?  I've got the MP91S MKII and MP31SWV servos.



Thanks!

Ed
