5. In case of short circuit or failure of power device transistor, the motor could make an uncontrolled
movement within a range up to 180 degrees in electrical angle (180 degrees in electrical
angle=1/50 of a turn) and then remain a stable position. It is necessary to verify that this limited
movement does not correspond to some risky conditions.
6. Be sure that SAFE TORQUE OFF function properly works at first machine start-up and at every
drive replacement. If input / output signals are not used correctly (for example due to miswiring),
the STO function doesn’t work properly and dangerous situation can occur.
