Safe torque off (STO)
￭
The drive has a Safe torque off (STO) function in accordance with IEC/EN 61800-5-2.
It can be used, for example, as the final actuator device of safety circuits that stop
the drive in case of danger (such as an emergency stop circuit).
When activated, the STO function disables the control voltage of the power
semiconductors of the drive output stage, thus preventing the drive from generating
the torque required to rotate the motor. The control program generates an indication
as defined by parameter 31.22. If the motor is running when STO is activated, it coasts
to a stop. Closing the activation switch deactivates STO. Any faults generated must
be reset before restarting.
The STO function has a redundant architecture, that is, both channels must be used
in the safety function implementation. The safety data given is calculated for redundant
use, and does not apply if both channels are not used.

Description
Warning: Current calibration is done at the next start.
Fault: Output phase current measurement fault.
The output current is more than the internal limit. This can
also be caused by an earth fault or phase loss.
A load unbalance that is typically caused by an earth fault in
the motor or the motor cable.
There is a short-circuit in the motor or the motor cable.
The intermediate DC circuit voltage oscillates due to missing
input power line phase.
Incorrect input and motor cable connection.
Intermediate DC circuit voltage is too high.
Intermediate DC circuit voltage is too low.
All three phases are not connected to the motor.
STO hardware diagnostics has detected hardware failure.
Contact ABB.
The Safe torque off (STO) function is active.
Break in embedded fieldbus communication.
Communication lost between drive (or PLC) and fieldbus ad-
apter.
The I/O extension module types and locations specified by
parameters do not match the detected configuration.
The motor ID run occurs at the next start.
The Safe torque off circuit 1 is broken.
The Safe torque off circuit 2 is broken.
