Minimum, non-
detected STO short
pulse
t < 400 µs
The Safety controller can transmit short pulses to STOx inputs for
diagnostics purposes. These pulses will be ignored by the safety
circuit and will not stop the power stage but can be read from
firmware for system diagnostics, see:
Register

48 V SELV (range from 8V to 60V; maximum failure voltage 60 V)
Motor Type
STO safety function is only considered when the drive is controlling
three-phase permanent
magnet synchronous rotating motors.
STO does not apply to DC brush motors.

Uncontrolled Motor Movement
In the event of a failure in the power stage,
the motor shaft may rotate up to 180º
electrical degrees.
It is responsibility of the customer to prevent any hazards
related ot this unexpected motor movement.
