Non-observance of the environmental and connection conditions may lead to loss of
safety functions.
• Be sure to observe the specified environmental and connection conditions, and
especially the input voltage tolerances
Note
Material damage due to unexpected movements
Failure of the motor controller output phase during STO status (simultaneous short
circuit of 2 power semiconductors in different phases) may result in a limited detent
movement of the rotor. The rotation angle / travel correspond to the pole pitch of the
applicable motor.
