We have The Money Pit (an Excello 408) wired so that the B axis amp is off and the brake is on by default.
As well - the pressure switch on the brake has to be "made" for the amp to even pull the ENABLE contactor in. I think that this was how it was set-up to begin with, but not 100% sure anymore. ???
But when dooing heavy werk - especially any real distance from center, it is somewhat easy to overpower the brake, and then the control sees the OUT OF POSITION value go out of the preset allowance, and then the brake is released, and in a cpl seconds _ once pressure builds, the amp kicks in and tries to correct it. (durring the cut!)
Currently, my amp needs tweaked, and when it engages it lunges a bit at first. All of these issues together add up to a heapin' helpin' of dissatisfaction!
It was believed that we would not want the amp live while the brake is holding, as it could/would overheat from fighting agginst the brake constantly. But just powering off the brake the B can drift a bit sometimes before the brake catches it. (.05* max)
Just for that fact alone I want to rewire and re-program it so that the amp stays on untill a few seconds after the brake seats.
Can any of you comment on how your machine is set-up?
This is essentially a HBM application, but HMC and maybe even A axis on a VMC info could be mentioned. Older - less smart drives/controlers may be more relivent?
This is on a retrofit, and we can make it doo whatever we want...
It would be swell to have the "lockdown" of a 1* index table AND the manouverability of a B axis.
