Note: If an error that cannot be corrected occurs, the motor controller changes to the "Not ready to
switch on" state and stays there. These errors includes an encoder error (e.g. due to missing shielding,
cable breakage)
8.1.2 Behavior after the "Operation enabled" state is left
Brake reactions
Different brake reactions can be programmed when leaving the "Operation enabled" state.
These include the transitions described below.
The following diagram shows an overview of the brake reactions.

Transition to the "Quick stop active" state (quick stop option):
In this case, the action stored in object 605A
is executed (see the following table).
