Note: The Safe motor temperature function is motor-specific. This is
the case also in ACS880 multidrives where multiple motors are
connected to the drive.
￭ Drives and modules
The module is available as a factory-installed option (+L537+Q971)
or as an add-on kit for ACS880 drives and modules.
To install the kit, the user:
• makes sure that the serial number of the drive/inverter module
starts with 1, 4, 7, 8, M or Y
• attaches the included ATEX label for the SMT function to the
drive/inverter module to ensure the ATEX compliance of the
safety circuit
• installs the option module to an option slot of the drive control
unit and sets the applicable drive parameters
• connects the PTC temperature sensors of the motor to the PTC
inputs of the option module
• connects the drive STO terminals to the STO output of the option
module (or to the FSO module and then configures the FSO
module to do the STO function).
￭ Cabinet-built drives
For cabinet-built ACS880 single drives and ACS880 multidrives, the
module is available as factory-installed options:
• +L537+Q971
• +L537+Q971+Q973 (with the FSO-12 module)
• +L537+Q971+Q972 (with the FSO-21 module)
• +L537+Q971+Q972+L521 (with the FSO-21 and FSE-31
modules).
The user connects the PTC temperature sensors of the motor to the
PTC inputs of the module.
