The Core state block returns the state of the target:
0 = FAULT: The target received an error signal and waits for a user acknowledgment to switch back to BLOCKED state (PWM disabled)
1 = BLOCKED: PWM disabled, the target waits for the enable command to switch to OPERATING and activate its PWM outputs.
2 = OPERATING: The PWM outputs are enabled.
The block also provides a second signal called “reset” that can be wired to the external reset input of PID controllers to keep the integrator at reset when the target is not in OPERATING state.
