COMMUTATION TRUTH TABLE
This table shows the Phase Output state versus
the state of the Hall-Effect and Direction Inputs.
Please note that the OM9369CM Hall-Effect
Inputs are Grey-encoded; that is, only one input
is allowed to change from one input state to
another at a time.
The commutation coding shown reflects Hall-
Effect sensors that are spaced at 120°
mechanical increments. Also, internal
protection logic disables all three Phase
Outputs when the Hall-Effect Inputs are set to
an illegal condition (i.e. all logic low or all logic
high).
