This chapter describes the Safe motor temperature function
implemented with the FPTC-02 module and the drive Safe torque off
function and gives instructions for the user.
Overview
To implement the Safe motor temperature (SMT) function, you can
connect the FPTC-02 module directly to the drive Safe torque off
(STO) circuit, or you can use it together with an FSO 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.
Safety functions in the FSO module can open the drive STO circuit,
which activates the STO function of the drive.
