    This chapter contains information on the guide and gives safety instructions and some other general information for the reader. Applicability This guide is applicable to the ACS880 drives and inverter modules with the ATEX- certified Safe disconnection function (option +Q971). Target audience This guide is intended for personnel who install, start-up, use and service the ATEX- certified Safe disconnection function (option +Q971) of the drive.

  • Page 8: The Atex-Certified Safe Disconnection Function

    The safety function described in this guide activates the Safe torque off (STO) function of the drive/inverter module. The STO function of the ACS880 drives is certified (SIL 3 according to EN/ IEC 61800-5-2 and IEC 61508). For a detailed description of the STO function, see the hardware manual of your drive/inverter module.

    The FSO safety functions module (FSO-12 or FSO-21) is an optional device used with the ACS880 drives to implement safety functions. When installed, it reserves the standard STO connection of the drive. In this case, the FSO module activates the STO function of the drive (that is, opens the drive STO circuit) either immediately or after a deceleration ramp.

    For more information, see the firmware manual. For Ex motors supplied by other motor manufacturers, contact the motor manufacturer for the correct value and your local ABB representative for instructions on how to make the parameter setting in the drive.

  • Page 24: Reset Method And Status Indications

    There are two ways to configure the motor overtemperature indication. Example 1 The ACS880 primary control program has two separate temperature monitoring functions. In this example, one of these functions (External event function 1) is configured to monitor digital input DI6 (you can also use another digital input). When off (0), the function triggers the user-selected indication and shows the user-defined message.
