Page 7: Introduction To The Manual
Introduction to the manual 7 Introduction to the manual Contents of this chapter This chapter describes the manual in short and gives some general information for the reader. Applicability The manual applies to the ACS800-01/04/04LC/04M/11/14/31/104/104LC and ACS800-U1/U4/U11/U31 drives and inverter modules which have the option +Q967: Safe torque off (STO). -
Page 8: Target Audience
8 Introduction to the manual WARNING! (With permanent magnet 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 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 in the drive hardware manual. -
