OK , MDI a M19 and let us know what happens .
DO NOT put tools in the drum till you get this resolved .
If the head comes down before spindle orient , it may not engage the drive key .
IT COULD BREAK OFF THE TOOL DRUM MOUNTS.
No air lines to the head ? an air cyl is what releases tools from the spindle .
Disconnected the spin brake ? ( is this what you are mistaking for a brake ?)
Actually the VFD induces a reversing voltage to stop the spindle , there is no mechanical brake as such .
