Update Notice

WARNING!
The Safe torque off function does not disconnect the voltage of the main
and auxiliary circuits from the drive. Therefore maintenance work on electrical parts
of the drive or the motor can only be carried out after isolating the drive system from
the main supply.
Note:
The Safe torque off function can be used for stopping the drive in emergency
stop situations. In the normal operating mode, use the Stop command instead. If a
running drive is stopped by using the function, the drive will trip and stop by coasting.
If this is not acceptable, e.g. causes danger, the drive and machinery must be
stopped using the appropriate stopping mode before using this function.
Note concerning permanent magnet motor drives in case of a multiple IGBT
power semiconductor failure:
In spite of the activation of the Safe torque off
function, the drive system can produce an alignment torque which maximally rotates
the motor shaft by 180/
p
degrees.
p
denotes the pole pair number.
Note:
If you add or modify the wiring in the drive safety circuits, ensure that the
appropriate standards (e.g. IEC 61800-5-1, EN 62061, EN/ISO 13849-1 and -2) and
the ABB guidelines are met.

Action
Additional information
Check the correct operation of the emergency stop
circuits from each operating location.
If the drive is equipped with the category 1
emergency stop function (Q952 or +Q964),
adjust the delay time of the emergency stop relay
and the deceleration time of the drive emergency
stop function. The factory default settings do not
necessarily meet the application needs.
Action
Additional information
Check that the Safe torque off function (option
+Q968, if installed) works:
Optional function. See delivery
specific circuit diagrams.
• Ensure that the drive can be run and stopped
freely during the commissioning.
• Stop the drive (if running), switch the input power
off and isolate the drive from the power line by a
disconnector.
• Check the STO circuit connections against the
circuit diagram.
