USB usage while drive running
The NXGPro+ has two interlocks that aect USB functionality. One is so that all USB port
functionality will not start from keypad while drive is either: Not CR3 Inhibited, Not Idle, or Not
Faulted. That is, the drive must be CR3 Inhibited, Idle, or Faulted to use USB functionality. The
other is that the drive cannot be started while any USB function is active processing the keypad
request. The latter requires an SOP ag ReadyToRun_I as part of the TempFlag01_O main ag.
