Re: Motor Brake makes G320 act wierd

Joe,

It sounds to me like the bake must be binding or you are releasind it
to late. When the drive powers up it must move 8 increments of
motion. This is to insure there is no "integrator windup". If the
brake is held when the drive comes out of reset, there will be a fist-
fight and the drive will lose against the brake.
