8 Introduction to the manual
WARNING! Frames nxDXT + nxR8i: The Safe torque off functionality is only
achieved through the XSTO connector of the inverter control unit. True Safe
torque off functionality is not achieved through the XSTO connectors of the supply
control unit. In the supply unit, the XSTO input must not be used for any safety function
purposes to ensure personnel safety. The Safe torque off function is supported by any
ACS880 inverter or drive firmware. It is not supported by supply firmware.
WARNING! (With permanent magnet or synchronous reluctance [SynRM] motors
only) In case of a multiple IGBT power semiconductor failure, the inverter system
can produce an alignment torque which maximally rotates the motor shaft by
180/p (with permanent magnet motors) or 180/2p (with synchronous reluctance [SynRM]
motors) degrees regardless of the activation of the Safe torque off function. p denotes the
number of pole pairs.
WARNING! Read and obey all safety instructions given for the drive in its
hardware manual. If you ignore them, injury or death, or damage to the equipment
can occur.
This manual does not repeat the complete safety instructions of the drive but it only
includes the instructions related to the scope of this manual.
