Parameters are not stored permanently on iHSV42 #18

mhier commented 1 year ago

I am using the tool for an iHSV42 motor (which has v606 firmware). In principle it works, I can change tuning parameters, plot the graph and optimise the parameters. When I remove the power from the motor though all parameter values are lost and everything reverts to default values on the next start. I am not sure whether this is really a problem of this nice tool, because I cannot get the original software to work at all (sees no connection, maybe it doesn't like my serial USB adapter).

Any hints are welcome!

EDIT: Maybe this is caused by the newer V606 controller?

I faced the same issue and finally seem to have solved it - testet with iHSV57 v603 and v606.1 motors that did not store the parameters permanently before.

After comparing the Modbus communication from the JMC software on Windows and iHSV-Servo-Tool on Linux on a logic analyzer the only difference I could see is that the JMC software re-reads the registers after writing new parameters to the servo. For whatever reason this did the trick for me - my updated fork is public at https://github.com/simonkuehling/iHSV-Servo-Tool if someone else stumbles over this as well.
