Procedure
Step Action Expected Result
13 Power on the Everest XCR with STO1= high,
STO2 = high.
-
14 Try to perform a "Motor Enable" (using
Motionlab 3 or network commands). Power stage can be enabled, allowing motor
rotation. Check it by software (system should
enter in motor enable state) or by hardware
(checking the Motor phases voltage with a
multimeter).
If power stage cannot be enabled it could be
caused by other faults not related with STO
(over-voltage, under-voltage, etc.)

but the STO function is
activated. Therefore, no torque
can be applied to the motor.
STO trip is reported to the MCU
and to the safety circuitry. This
