AUTOMATIC TRANSITION
(black transitions in the image below)
Operation enable is the only state in which the power stage is enabled.
Using Shutdown option code it is possible to define the drive behaviours in transition 8. If
Shutdown option code is equal to 1, then drive set the controlled variable (speed in Profile
velocity mode and Profile position mode, torque in profile torque mode) to 0 and perform a
linear ramp. If Shutdown option code is equal to 0 then the drive directly disable power stage
without controlling the controlled variable.
Disable operation option code does the same operation in transition 5.
