Table 7- 1. Explanation of the Control Supervisor State Transition Diagram
Start Forward, Start Reverse, Change to Forward, Change to Reverse, and Stop (Not Faulted Stop) are static
outputs of the Control Supervisor state machine. They are commands to the drive when CtrlFromNet=1. When
CtrlFromNet=0, control commands are from another source.
Drive State for Control Supervisor:
DN_NON_EXISTANT
0
DN_STARTUP 1
DN_NOT_READY 2
DN_READY 3
DN_ENABLED 4
DN_STOPPING 5
DN_FAULT_STOP 6
DN_FAULTED 7
