Ok ,hang on… There was one instance when I was testing the initialization mod
where I found the acceleration/ deceleration parameters where reset. I had
been turning the vfd on/off and playing with various parameters so I just kind
of ignored it but was a little surprised. Yesterday I was doing part and
thought that the spindle was taking longer to change speeds (in CSS) than it
should and was going to check that again and forgot before I left. I have
fairly aggressive accel/decel. When I get back to the shop (today or tomorrow
perhaps) I will be checking to see if my accel/decel is correct. Now you have
me wondering. I also set several other parameters, I have a custom Volt/Hertz
curve set to be able to run my motor down to 50rpm without having the vfd
current limit and shut off. I do know that that is working.
Do other parameters get reset? And when it happens do all parameters get reset
or just some? Like p0.00-p0.04 the motor parameters? Seems like that would
cause a serious issue if those got reset.
